Hi ,
I'm so sorry you are going through this. I have experienced some fatigue when going off of prednisone, but not as extreme as what you are describing. Prednisone is usually pretty effective for me, so as I taper off the underlying fatigue as well as exhaustion from enduring pain can start to return. I also don't have the jolt that higher doses of corticosteroids give me.
Are you and your doctor examining longer-term treatment options for your pain and fatigue? When I've been experiencing a lot of fatigue, my doctor has tweaked my treatment regimin in an effort to decrease this RA symptom. If you don't feel that your doctor is giving your symptoms adequate attention, I recommend you seek out a second opinion. Sometimes there aren't any additional, viable options, but if there are it is worth finding out.
I know all too well how hard it is to seek out answers and advocate for yourself while not feeling well. I hope that you can see some relief soon!
Wishing you all the best,
Tamara
