Pyelonephritis symptoms and conditions

Hi...Am 33 years and had been on prednisone for 4 months till about a month ago. It was in June last year that I was down with Viral hepatitis along with pyelonephritis. I was eventually diagnosed with Autoimmune hepatitis and therefore administered this drug with an high of 40mg for two and gradually tapered subsequently.
Two months of medicines and I had this pain in my thighs especially when I had to get up after lying sedentary. After 1.5 months subsequently the pain worsened to now include all my joints including the leg muscles. Things have really become more painful now. The gastroentorologist who put me on this drug has advised me to see a rheumatologist. Now I am torn between trying to understand whether this is a part of my treatment or my ailment (rheumatoid arthritis is also an auto immune disorder) and only praying that it is a part of the treatment.
The Doctor's have not been clear on how long this pain will persist. Regular walking, getting up, getting out of the car, turning the cap of a bottle is painful and getting worse with my ankles and knees swelling.
The moon face, the hump, the acne are all ebbing. However this pain is killing. Anybody has any idea how long the pain will last?
Thank you and best wishes to you.

And here I thought what I was feeling was my illness not getting better. Seems that many people suffer some of the same side effects that I am. I have been takine Levaquin for Pyelonephritis for 10 days now. I run fever in the mornings, I am always achy, my joints hurt, I'm tired all the time....maybe (hopefully) now that I'm through with my meds I'll get better!
