Arteritis is a condition in which the arteries swell. Arteries are blood vessels that carry oxygen through the body from the heart.
Giant cell arteritis, or GCA, can occur in the arteries of the arms, upper body and neck. However, it usually affects the arteries that are above and in front of the ears on both sides of the head. This type of GCA is also sometimes called the temporal arteritis. Headache is the most common symptom. However, some patients might experience pain while chewing, blurred or reduced vision, or even blindness in one or both eyes.

How are GCA and PMR related?
About 15% of people with PMR have GCA, and about half of people with GCA have PMR. They can have these diseases at the same time, or CGA can develop after PMR.
What causes these conditions?
No one knows what causes GCA or PMR. Immune system problems and aging are possible factors. A physical exam and blood tests are needed to find out if you have this condition.
Who gets these conditions?
You are more likely to develop GCA and PMR is you are older than 50 years of age. They are most common in women between 70 and 80 years of age.
How are these conditions treated?
Your doctor may prescribe a steroid often used to treat inflammation called prednisone. Once you start taking prednisone, you should feel better quickly. You may need to take this medicine for up to 2 years. Taking prednisone for along time can raise your blood pressure and your blood sugar level, or weaken your bones. Your doctor will need to keep checking you for the these side effects during your treatment.
