This is all so new to me. Had a headache for 18 days, sore scalp, night sweats and sore jaw although thought this was because of a careless tooth extraction in July 2014. After seeing two different doctors, I was sent to A&E and was immediately diagnosed with GCA. No biopsy was done. Hospital put me on 40 mg prednisolone but when I saw a third local doctor who has treated three other cases in the past 3 years, he upped it to 50 mg prenisolone. I have sinced dropped to 40 mg and am fine. My question is.....if he drops it to say 30 mg after next bloods check, how quickly would I notice a relapse or is there no hard and fast rule?
