Hello,
If you go to both the lupus and fibro boards and scroll back, you will see this has been discussed in depth. I too have it and have posted lots about it. My best treatment for it was steroid injections. I haven't had these for a long while because I had heart surgery and of course that area is too tender now.
I am just getting through a full rib cage flare of it which was brought on by having stomach surgery, with the pushing and pulling about on the table, and as I can't take any painkillers because of medications I already take for lupus and heart problems, then I have to take it very easy when it happens.
Hope this helps.
