Hi Palyn,
Oh yes, my chest area is one of my biggest areas of pain. My rheumy told me it was likely costochondritis but that usually clears in a matter of months. I can only assume it is the intercostal muscles causing all the pain. At times I can barely touch my sternum. Now my major area is the second rib which is a determining fibro factor.
Hope you feel better. Doesn't it help to realize you are not alone??
Patsie
