Back pain when coughing is a common and often unsettling symptom. The act of coughing, a natural reflex to clear airways, involves significant physical exertion and places considerable stress on the body. This sudden, forceful action can range from minor discomfort to sharp, intense pain, often signaling an underlying issue that warrants attention.
How Coughing Affects Your Back
When you cough, muscles in your chest and abdomen contract forcefully, which can strain the muscles and ligaments in your back. This sudden contraction is a reflex designed to expel air and foreign substances from the airways.
The process also significantly increases intra-abdominal pressure (IAP). This elevated pressure, resulting from the coordinated contraction of thoracic, abdominal, and pelvic muscles, pushes the diaphragm upwards and generates the expiratory force needed for a cough. This internal pressure can exert additional strain on spinal structures, potentially leading to or worsening back pain. If your body is forced into a bent-over position during a strong cough, it can also increase strain on back muscles.
Underlying Spinal Conditions
Coughing can exacerbate pre-existing spinal conditions. One common issue involves herniated or bulging discs, which are cushions between spinal bones. When you cough, the increased pressure can cause a damaged disc to press further on nearby nerves, leading to pain that may shoot into an arm or leg.
Degenerative disc disease, characterized by age-related wear and tear on spinal discs, also makes the spine more susceptible to pain during coughing. Weakened discs are less able to absorb the pressure from a cough, leading to increased discomfort. Spinal arthritis, or osteoarthritis, involves inflammation in the spinal joints, which can be aggravated by the movement and pressure associated with coughing.
Sciatica, a condition resulting from irritation or compression of the sciatic nerve, can also be worsened by coughing. Pressure from a cough can further compress the nerve roots that form the sciatic nerve, intensifying symptoms like pain, tingling, or numbness that radiate down the leg.
Other Health Issues Causing Back Pain with Coughing
Back pain during coughing can sometimes stem from causes outside the spine or be a symptom of a broader health issue. Respiratory infections, such as bronchitis, pneumonia, or pleurisy, can lead to back pain. Inflammation in the lungs or the surrounding membranes (pleura) can radiate pain to the back, especially with the deep breaths and forceful exhalations involved in coughing.
Kidney problems, including kidney stones or infections, can also cause back pain that feels worse with coughing. Kidney pain is typically felt in the flank area, on either side of the lower back, between the ribs and hips. While kidney pain itself may not worsen with movement, the jarring motion of a cough can aggravate the discomfort associated with these conditions.
Muscle spasms, not directly caused by the cough but aggravated by it, represent another potential source of pain. When muscles involuntarily contract, coughing can trigger or intensify these spasms, leading to significant discomfort. This can occur due to factors like dehydration or fatigue, which can be worsened by persistent coughing.
When to Consult a Doctor
While many instances of back pain with coughing resolve on their own, certain symptoms warrant professional medical attention. You should seek medical help if the pain is severe or progressively worsens over time. Pain that does not improve after a few days or persists for more than a week also suggests a need for evaluation.
It is important to consult a doctor if the back pain is accompanied by fever, chills, or night sweats, as these can indicate an underlying infection. Numbness, tingling, or weakness in the legs or arms are also concerning signs, as they may point to nerve compression or damage. Loss of bladder or bowel control is a serious “red flag” symptom that requires immediate medical attention. Additionally, pain that occurs after a fall or injury should be assessed by a healthcare provider.
