I’m thinking many things will be blamed on the shots but I have concerns myself. My last shot was April 8 and a month later was having fatigue and now (July) can’t walk without pain. GP says it looks like PMR so waiting on urgent referral list to see rheumatologist and long wait for my life has deteriorated immensely. The depression isn’t helping. You’re lucky you started on the prednisone so soon. I’ve read that calcium and vitamin D should be taken while on prednisone.
