Costochondritis is an inflammation of the chest wall. It seems to be another symptom of fibro. I went to the er twice feeling like I was having a heart attack before they diagnosed me with it. With chest pain it is always a good idea to get checked out to be sure. Good luck and I hope you feel better soon. I take ibuprofen and use ice packs to help the inflammation go down.

Yes, all the time. Very unpredictable. Sometimes it gets worse on days that I either carried things too long or that were too heavy for too long. Then sometimes it doesn’t even matter.
