I was diagnosed GCA by a positive biopsy in July 13 and have been tapering from 60mg to 4mg. I have not had a flare in this time apart from a short lived reaction when I have reduced my dose. I cut down to 4mg from 5mg recently and have now got a painful left eye and headaches. I was fine on 5mg have been on that dose since May but hadn't tried to reduce because my husband was ill. Can I try increasing my dose back up to 5mg? I am desperate not to go back up to a high dose after all this time I had a really bad reaction to the high doses at the start of my treatment.
