I have had GCA for three years this month. After being on 1 mg. for 2 months, my doctor reduced me to 1-0-1-0-1-0. I started having upper leg pain behind my knee. I saw him again and he said "well, go back to 1 mg. per day until you are better. Since then (2months later) I have neck pain, right arm pain and shoulder pain. Is it possible that I have developed PMR? May I have suggestions on what to do? Thanks so much! Here I thought " good-bye GCA and now something new?????
