I am sorry to hear you are dealing with so much. I too have gone in for obstruction pain and end up in the hospital for a few days and then they mention in passing that the scans also showed a kidney stone. It is very confusing.
I too was on prednisone for a long time and actually had surgery to get my life back. I am now on Endocort and it works for me.
I do get a lot of sinus infections so Levaquin is also my friend.
