The most common first sign of temporal arteritis is a new, persistent headache, typically felt in the temples on one or both sides. This headache often appears alongside scalp tenderness, jaw pain while chewing, and general feelings of fatigue or fever. The condition, also called giant cell arteritis (GCA), involves inflammation of medium and large arteries, and it almost exclusively affects people over 50. Recognizing the early signs matters because untreated temporal arteritis can cause permanent vision loss.
New Headache and Scalp Tenderness
A headache that feels different from any you’ve had before is the symptom that sends most people to their doctor. It tends to settle around the temples, though it can spread across the forehead or to the back of the head. The pain is often described as a steady, boring ache rather than a throbbing pulse. It may be worse at night or when you lie down.
Scalp tenderness frequently accompanies the headache. You might notice it when brushing your hair, resting your head on a pillow, or even wearing glasses. Some people can feel a thickened, ropey temporal artery along the side of the head that is tender to the touch. This tenderness reflects inflammation in the artery walls just beneath the skin.
Jaw Pain While Chewing
Nearly half of people with GCA experience jaw claudication, a distinctive symptom where the jaw muscles ache or tire during chewing and feel better once you stop. It happens because inflamed arteries can’t deliver enough blood to the jaw muscles when they’re working hard. The sensation is similar to how a leg cramp builds during exercise and fades with rest. Some people notice actual stiffness or limited movement of the jaw joint, and a smaller number experience similar fatigue in the tongue while eating or swallowing repeatedly.
Jaw claudication is one of the most specific early clues to temporal arteritis. Many conditions cause headaches, but the combination of a new headache with jaw pain during meals is a strong signal that warrants urgent evaluation.
Vision Changes
Visual symptoms are the most serious early warning sign. They can include brief episodes of blurred vision, double vision, or temporary loss of sight in one eye (sometimes described as a curtain or shade dropping over part of the visual field). These episodes may last only seconds or minutes and then resolve completely, which can tempt people to dismiss them. But they often signal that the blood supply to the optic nerve is compromised, and permanent blindness can follow if inflammation isn’t controlled quickly.
Vision loss from GCA is almost always irreversible once it occurs. That urgency is why doctors will start high-dose corticosteroid treatment the moment temporal arteritis is suspected, even before confirmatory tests are complete.
Fatigue, Fever, and Weight Loss
Many people with temporal arteritis first notice vague, whole-body symptoms that don’t immediately point to an artery problem. Low-grade fever, deep fatigue, loss of appetite, and unexplained weight loss can precede or accompany the headache and jaw symptoms. These “constitutional” signs reflect widespread inflammation and can persist for weeks before more localized symptoms appear.
Because these symptoms overlap with many other conditions, from infections to cancers, they’re easy to attribute to something else. In someone over 50 who also develops a new headache or scalp tenderness, though, they become important puzzle pieces.
Muscle Aches and the PMR Connection
About 50 percent of people diagnosed with GCA also have symptoms of polymyalgia rheumatica (PMR), an inflammatory condition that causes pain and stiffness in the shoulders, upper arms, hips, and thighs. The stiffness is usually worst in the morning and can make it difficult to get out of bed, raise your arms overhead, or climb stairs. PMR sometimes appears weeks or months before the headache and jaw symptoms of temporal arteritis develop.
The overlap works in the other direction too: 5 to 15 percent of people initially diagnosed with PMR eventually develop GCA. If you’ve been diagnosed with PMR and notice a new headache, scalp tenderness, or any change in your vision, that combination deserves prompt medical attention.
Less Common Early Signs
Roughly 10 percent of people with temporal arteritis develop respiratory symptoms, including a persistent dry cough, sore throat, hoarseness, or a choking sensation. These are the initial complaint in about 4 percent of cases. Some people report pain that feels like it’s coming from the sinuses, ears, or teeth, even though those structures are healthy. These atypical presentations can delay diagnosis because neither the patient nor the doctor immediately thinks of an artery problem.
A dry cough alone, however, is never the only symptom of temporal arteritis. It will always be accompanied by other signs, even if those signs are subtle, like mild scalp tenderness or unexplained fatigue.
Who Is Most at Risk
Temporal arteritis almost never occurs before age 50. The average age at diagnosis is about 77. Women develop GCA roughly twice as often as men. Data from a large Spanish registry of over 1,600 patients found an annual incidence of about 10 per 100,000 in women compared with roughly 5 per 100,000 in men. People of Northern European descent have higher rates than other populations, though GCA occurs in all ethnic groups.
How Temporal Arteritis Is Diagnosed
Blood tests are usually the first step. Doctors look for two markers of inflammation: the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). In people with GCA, these values are typically elevated well above normal. The 2022 classification criteria from the American College of Rheumatology and EULAR give significant diagnostic weight to an ESR of 50 mm/hour or higher, or a CRP of 10 mg/L or higher.
Imaging plays an increasingly important role. An ultrasound of the temporal arteries can reveal a “halo sign,” a dark ring around the artery that indicates swelling in the vessel wall. Under the current classification system, this ultrasound finding carries the same diagnostic weight as a temporal artery biopsy, which involves removing a small segment of the artery and examining it under a microscope. A biopsy remains the gold standard in many centers, but the availability of skilled ultrasound has made non-invasive diagnosis more common.
What Treatment Looks Like
Treatment typically begins with 40 to 60 mg of prednisone daily by mouth. Because vision loss is nearly irreversible, doctors start this dose as soon as temporal arteritis is suspected, often before biopsy results come back. Most people notice a dramatic improvement in headache, jaw pain, and fatigue within days of starting treatment.
The initial high dose is then gradually tapered over months, sometimes a year or longer, depending on how symptoms and blood markers respond. The tapering process requires patience and close monitoring because reducing the dose too quickly can trigger a flare. Long-term steroid use carries its own risks, including bone thinning, blood sugar changes, and increased infection susceptibility, so your doctor will typically monitor for those effects throughout treatment.
