I had a Medrol injection early December and it was brilliant. I started hydrochloroquine end of Dec but symptoms started creeping back in during February. 4 days ago I had a 2nd injection, but i don’t feel it has been as successful. My fingers have gone down but first finger isn’t perfect. Toes are now great. Temperature control is better, but I’m still very tired and my knees still feel like they’re burning on an evening. Do steroids sometimes stop working as effectively after a period of time?
