I am feeling almost as much pain as I started with a year ago. I am worried because I had sore to touch spots on my scalp for quite awhile before the excruciating pain came over me one morning as I woke. Has anyone hav this scalp symptom ? It worries me now as I see it is a symptom of Giant Cell. I had my blood test for pmr 3 weeks ago (4mgs) and it was fine, so I am wondering why this pain is coming back at 2 mgs. Anyone experienced this?
