I am sharing this in case others are on a similar path. I have had GCA for a year and gone from 40mg prednisolone to my current level of 4mg. No problems (apart from becoming pre-diabetic with raised blood sugar levels) however markers have normalised and mercifully - no flares. Saw the rheumatologist today for 6 month review and he says with present progress a 6 month review and discharge the next step. Shedding the medicine cabinet is something to look forward too and celebrate!
