@rocksology Sorry you are going through this horrible ordeal.
Was bloodwork done the first month you were taking prednisone? They are wanting me to have bloodwork done every month-basic metabolic panel and C-reactive protein. Have to seen a Rheumatologist? Seems like having someone that can manage all of the things you are dealing with would be great. Im sorry to make a general statement about doctors but sometimes they focus on their specialty or as I say: " body parts doctors", where they can't seem to manage different illnesses or conditions occurring at the same time. I'm sure it's tough to do but it's necessary.
I recently had blood work done and my eGFR was 49 so I made an appointment to discuss. I'm currently on 8mg once a day prednisone and working on slow tapering.
