... worse, and now are disabling. Mostly on left side, but also forehead and back of head. Jaw pain, fatigue, depression, and a little scalp tenderness (but that may be just because of headache.) My GP is looking into GCA. Question - I have bulging temporal arteries when I am in a bad headache, especially the left side. This goes away when head is not as bad. Is this a symptom? Also, VERY heavy painful back of head, and worsens much with physical activity. Does this sound like GCA? Only lying down helps, and it is helping less as time goes on... thanks for any feedback
