I've had GCA diagnosed since Jan 2015 and am currently on 20 mg prednisilone, and have generally been ok, apart from a flare up last June when tapering down to 15 mg. However, I've had a low grade headache and a feeling of eye pressure for the last 4-5 days. I had a regular consultant meeting yesterday and reported this; he took a blood sample, and told me that all the markers were normal, and that there was no sign of inflammation. He advised I increased the pred to 25 and arranged to see me in a week. Despite the increased steroid, it's got worse today. Has anybody else experienced this - could it be the steroid? I've every confidence in my consultant, but I wondered if it might be a side effect.
