Ginny, I did a search on sacroiliitis and found one of your posts from about a year ago. I hope you don't mind if I ask you a few questions.
I've been dealing with (or should I say suffering with) sacroiliitis for about 8 months now. It started on one side but is now bilateral. I've tried oral steroids and am currently taking NSAIDs, but I'm really having a flare and am in significant pain (I'm sure you can relate).
I saw in your post that you use a topical steroid cream. Has it helped you much? Do you get it OTC or Rx? What type of PT did you do? Are you still dealing with sacroiliitis? Have you tried anything else that was helpful?
Thank you so much in advance. The past week or so I've been unable to sleep or walk very well due to the pain in my SI joints (in addition to the fibro 
), and I would appreciate any advice (from anyone else who has dealt with sacroiliitis too 
).
