Coughing is one of the most physically demanding things your body does reflexively, and the muscle pain that follows is a direct consequence of that effort. A single strong cough activates muscles across your neck, chest, abdomen, back, and pelvic floor in a rapid, coordinated contraction that can generate internal pressures comparable to heavy weightlifting. When you cough repeatedly over hours or days, those muscles fatigue, strain, and sometimes sustain real injury. The story behind cough-related muscle pain, though, goes beyond simple overuse.
Coughing Is a Whole-Body Muscular Event
Most people think of a cough as something that happens in the throat or lungs, but the actual force comes from muscles throughout your torso. Research measuring electrical activity in muscles during coughing has identified at least seven distinct muscle groups that fire during a single cough: the scalene muscles in the neck, the sternocleidomastoid (the large muscle running from behind your ear to your collarbone), muscles between the ribs, the diaphragm, and both the external obliques and the rectus abdominis in your abdomen.1Journal of Electromyography and Kinesiology. Respiratory muscle activation and action during voluntary cough in healthy humans Each cough involves a three-phase sequence: you inhale deeply, your glottis (the opening between the vocal cords) slams shut while your chest and abdominal muscles contract against the closed airway, and then the glottis opens and air rushes out at high speed. That middle phase, where everything contracts against a sealed airway, is where the real muscular strain happens.
Reflex coughs, the involuntary kind triggered by an irritant or infection, are actually harder on your muscles than coughs you produce on purpose. Studies comparing the two found that reflex coughs activate all of the relevant muscles simultaneously and with roughly twice the electrical intensity of voluntary coughs at the same airflow rate.2Thorax. Differences in motor activation of voluntary and reflex cough in humans In a voluntary cough, your body recruits muscles in a staggered sequence, giving each group a slightly longer window to do its work. In a reflex cough, everything fires at once in a shorter, more explosive burst. That simultaneous activation means more peak force on every muscle involved, and less opportunity for any single group to share the load gradually. If you have ever noticed that the uncontrollable coughing fits during a bad cold feel more punishing than clearing your throat on purpose, the physiology backs that up.
Abdominal Muscles Bear the Heaviest Load
The muscles most commonly sore after persistent coughing are in the abdomen, and for good reason. Your rectus abdominis and obliques are the primary engines that generate the pressure needed to expel air from your lungs during the explosive phase of a cough. Measurements of intra-abdominal pressure during coughing have recorded peak values around 140 to 165 cm of water pressure, which is substantial enough to rival the forces produced during strenuous exercise.3PubMed Central. Intra-abdominal Pressures during Voluntary and Reflex Cough Imagine doing dozens or hundreds of intense abdominal crunches over the course of a day with no warm-up, no rest periods, and no ability to stop. That is roughly what happens to your core muscles during a bad bout of bronchitis or flu.
The soreness most people feel is delayed-onset muscle pain from repetitive eccentric and concentric loading. Your abdominal muscles contract forcefully, then relax, then contract again with each cough. Over dozens of cycles, the muscle fibers sustain microscopic damage, just as they would during an intense gym session. This is the dull, tender ache you feel across your midsection when you press on it or try to sit up the next morning.
In rare but well-documented cases, the force can go beyond soreness and cause a genuine abdominal wall injury. Intense contraction of the rectus abdominis can generate enough shear force to tear the muscle itself or damage the epigastric blood vessels running along its back surface, leading to a condition called a rectus sheath hematoma, essentially a pocket of blood collecting inside the muscle’s covering.4PubMed Central. Cough-induced rectus sheath hematoma in a healthy adult male – a case report This can happen even in otherwise healthy adults with no underlying bleeding disorders. Case reports describe patients who developed sudden, severe abdominal pain and a palpable lump after violent coughing episodes, with imaging confirming the hematoma.5JMA Journal. Urgent Rectus Sheath Hematoma Induced by Severe Coughing If abdominal pain from coughing is sharp, localized to one spot, or comes with visible bruising or swelling, that warrants a trip to the doctor rather than waiting it out.
Chest Wall Pain and the Joints Between Your Ribs
Pain in the chest during or after coughing often gets mistaken for something cardiac or pulmonary, but musculoskeletal chest wall problems are a common and underappreciated source. The thoracic wall is a complex structure with muscles layered between every rib, cartilage connecting ribs to the breastbone, and small joints where ribs attach to the spine. Any of these structures can become inflamed or strained from the repetitive mechanical stress of coughing.
Costochondritis, an inflammation of the cartilage where ribs meet the sternum, is one of the more frequent culprits. It produces a sharp or aching pain right along the breastbone that worsens with deep breathing, twisting, or coughing. The intercostal muscles, the small muscles sandwiched between adjacent ribs, can also strain from repeated coughing. These muscles stretch and contract with every breath and every cough, and when coughing becomes frequent, they can develop the same kind of overuse injury that any other muscle would. The clinical literature identifies costochondritis, traumatic muscle pain, and arthritis of the sternal and rib joints as common musculoskeletal causes of chest pain.6PubMed Central. Musculoskeletal chest wall pain These conditions are not dangerous, but they can be genuinely painful and sometimes last weeks after the cough itself has resolved.
The tricky part is that chest wall pain from coughing can feel alarmingly similar to pleurisy, which is inflammation of the lining around the lungs and is often associated with pneumonia or other infections. Both hurt more with deep breaths and coughing. A key difference is location and tenderness: musculoskeletal chest wall pain tends to be reproducible when you press on a specific spot, while pleurisy generally is not. If you are running a fever alongside sharp chest pain that worsens with breathing, an infection-related cause deserves evaluation.
When Coughing Actually Cracks a Rib
It sounds extreme, but coughing hard enough to fracture a rib is not as rare as you might expect. A study analyzing 90 patients at a single center found 154 rib fractures caused by coughing alone, most frequently affecting the fourth through ninth ribs and landing on the anterolateral aspect, meaning the front-side curve of the rib.7PubMed Central. Cough-induced rib fractures: A comprehensive analysis of 90 patients in a single center The most commonly fractured rib was the sixth. These fractures were overwhelmingly associated with certain risk factors: about two-thirds of patients were postmenopausal women, more than a third had metabolic bone disease (conditions that weaken bone), and about a fifth had chronic cough.
A separate series at the Mayo Clinic painted a similar picture. In that group of 54 patients with cough-induced rib fractures, the average age was 55, roughly four out of five were women, and bone density testing in about half the group revealed osteopenia or osteoporosis in most of those tested.8Mayo Clinic Proceedings. Cough-Induced Rib Fractures Fractures were associated with chronic cough lasting three weeks or longer in the majority of cases. Another study found that patients on long-term high-dose steroids for conditions like COPD or asthma were at elevated risk, likely because corticosteroids accelerate bone loss over time.9PubMed. Spontaneous rib fractures Bone density testing in that group revealed high fracture risk in every patient.
The pain from a cough-induced rib fracture is sharp and well-localized, typically worsening with each subsequent cough, deep breath, or any movement that shifts the ribcage. It is worth knowing that these fractures do not always show up on a standard chest X-ray. CT scans are significantly better at catching them. If your cough-related pain is pinpoint, severe, and not improving after a couple of weeks, imaging beyond a basic X-ray may be necessary.
How Viral Infections Add Muscle Soreness on Top of Cough Strain
If you have noticed that your muscles hurt everywhere during a bad cold or flu, and not just in the areas involved in coughing, the infection itself is partly responsible. Viral muscle soreness is a recognized phenomenon that occurs alongside many respiratory infections independent of any coughing. Recent research has begun to trace the mechanism: during viral infections, a signaling molecule called LCN2 is released from brain cells called astrocytes into the bloodstream. This molecule disrupts how muscle cells process energy, causing lactate to accumulate in muscle tissue, essentially the same substance that builds up during intense exercise and contributes to that burning sensation.10PubMed Central. Astrocytes-derived LCN2 triggers EV-A71-induced muscle soreness via accumulating lactate In animal studies, mice lacking the gene for this molecule maintained stronger grip force and more stable movement after infection, suggesting it plays a direct role in the achiness you feel.
This means that during a respiratory illness, you get a double hit: the virus itself is making your muscles more tender and sensitive through systemic inflammation, while the repetitive coughing is simultaneously pounding those already-sensitized muscles with high-force contractions. That combination explains why the muscle pain during a bad respiratory infection can feel disproportionate to the amount of coughing you are doing. Your muscles hurt both because of what the infection is doing to them chemically and because of what the coughing is doing to them mechanically.
Whooping Cough and the Dangers of Prolonged Paroxysms
Among respiratory infections, whooping cough (pertussis) deserves special mention because it produces uniquely intense and sustained coughing paroxysms that can cause injuries most people associate only with trauma. A coughing fit during pertussis can last a minute or more, with rapid-fire coughs followed by the characteristic “whoop” as the person gasps for air, only to start coughing again. These episodes can repeat many times per day for weeks.
The musculoskeletal toll of pertussis coughing goes well beyond typical soreness. Case reports document patients developing rib fractures, pneumothorax (a collapsed lung from air leaking through the chest wall), and severe muscle tears from the sustained violence of pertussis paroxysms.11PubMed Central. The potential dangers of whooping cough: a case of rib fracture and pneumothorax A complicating factor is that pertussis in adults often begins with symptoms that look like a common cold, leading to delayed diagnosis. By the time the paroxysmal coughing stage develops, the patient may already have been coughing hard for a week or two, with accumulating muscle damage. Adults who were vaccinated in childhood may have waning immunity and still contract pertussis, though usually with milder symptoms than an unvaccinated person would experience. If a cough has been escalating in intensity over several weeks and is producing violent, uncontrollable fits, pertussis testing is worthwhile.
Why Some People Are More Vulnerable
The same coughing illness can leave one person with mild abdominal tenderness and send another to the emergency room with a rib fracture or hematoma. Several factors tilt the odds.
- Bone density: Postmenopausal women and anyone with osteoporosis or osteopenia face a much higher risk of cough-induced rib fractures. Long-term steroid use for respiratory conditions further weakens bone and creates a vicious cycle: the disease causes coughing, the treatment weakens the ribs, and the coughing breaks them.
- Aging muscle: As muscles age, they lose some of their ability to absorb and recover from repetitive strain. The scientific literature notes that the secondary injury response and recovery from contraction-induced muscle damage are impaired with aging, though the exact mechanism is still debated.12PubMed Central. An Old Problem: Aging and Skeletal-Muscle-Strain Injury Maintaining muscle health through regular activity may raise the threshold at which coughing causes injury.
- Anticoagulant use: Blood thinners do not make you cough harder, but they dramatically increase the risk that a small vessel tear in the abdominal wall will turn into a significant hematoma rather than a minor bruise that reabsorbs on its own.
- Pre-existing respiratory disease: Chronic conditions like COPD, asthma, or bronchiectasis mean more frequent and more forceful coughing over longer periods, which compounds wear on the musculoskeletal system.
COVID-19 pneumonia was specifically associated with a higher rate of multiple rib fractures in one study, likely because of the intense, prolonged coughing it could produce combined with the systemic inflammatory effects of the infection.7PubMed Central.

Back Pain, Pelvic Floor Strain, and Other Overlooked Areas
The abdominal and chest wall muscles get most of the attention, but coughing sends force through other regions too. Lower back pain during coughing bouts is common and has a straightforward explanation: the sharp spike in intra-abdominal pressure that accompanies each cough also loads the lumbar spine. If you already have a bulging or herniated disc, the pressure increase from coughing can push disc material against a nerve root, producing a flash of pain or sciatica. Many people first notice a disc problem specifically because coughing, sneezing, or straining makes the pain flare.
The pelvic floor muscles, which form a sling across the bottom of the pelvis, also contract in response to rising abdominal pressure during coughing. Research on tasks that raise trunk pressure has shown that higher pressure loads cause measurable straining of pelvic floor structures.13Physiological Reports. How does the pelvic floor respond to modulations in trunk pressure induced by a variety of voicing tasks? A cross-sectional, observational study For people with weak pelvic floor muscles, especially women after childbirth or older adults, the repeated pressure spikes from coughing can cause pelvic pain and may worsen stress urinary incontinence. The leaking that some people experience during coughing fits is a direct consequence of the pelvic floor being overwhelmed by the pressure generated above it.
Neck muscles get involved too, particularly the scalene and sternocleidomastoid muscles, which help elevate the ribcage during the inhalation phase of each cough. Soreness along the sides and front of the neck after a coughing illness is not unusual, and people sometimes mistake it for swollen glands or a throat infection spreading. If the tenderness is in the muscle belly itself rather than in a lymph node, it is likely muscular.
Reducing Pain While You Recover
If coughing has already left you sore, the most effective short-term strategy is reducing the force and frequency of the coughs themselves. Over-the-counter cough suppressants containing dextromethorphan can blunt the reflex, and honey has modest evidence behind it for soothing nighttime cough in adults and children over one year old. Treating the underlying cause, whether that is an antibiotic for a bacterial infection or an inhaler for reactive airways, will also shorten the total duration of coughing.
For abdominal soreness specifically, a simple technique that many people discover instinctively is bracing the abdomen with a pillow or folded towel during coughs. Holding a cushion firmly against your midsection provides external support that reduces how far the abdominal wall has to stretch during each cough. Research on abdominal binders after major surgery found that patients using a binder experienced less increase in pain and symptom-related distress compared to those who went without one.14PubMed Central. The Effect of Abdominal Support on Functional Outcomes in Patients Following Major Abdominal Surgery: A Randomized Controlled Trial The same principle applies to cough-related strain: external support dampens the peak force on already-sore muscles.
Standard anti-inflammatory pain relievers like ibuprofen can help with the muscular soreness and any associated costochondral inflammation. Heat applied to sore muscles between coughing episodes can ease tension, while ice may be more appropriate if there is a specific area of acute injury or swelling. Gentle stretching of the torso and neck muscles, when tolerated, keeps them from tightening up further during recovery. For anyone experiencing pain that is sharp, localized, worsening despite the cough improving, or accompanied by bruising, fever, or trouble breathing, evaluation by a clinician is the right call, because the line between muscle strain and a fracture, hematoma, or pleural problem is not always obvious from the outside.
