It may be Costochondritis. An inflammatory condition that is more of a secondary symptom in fibromyalgia. Pian in ribs, sternum or breastbone. Sharp stabbing pains that in crease with movement or deep breath. May stem from viral , bacterial or fungal infections. More prevalent in left side side of rib cage. Avoid stretching, or massaging while inflamed or active. Alternate heat and cold applications. There is a face book page called living smarter with Fibromyalgia. I got that info from that page and it is very helpful.

There is something called the MS hug. People with MS get it randomly sometimes. I find that many of the symptoms of fibromyalgia and MS, even though they are not the same disease, overlap. I think it is because they are both nerve issues.

I was going to ask about this and then found this. My pain is generally in the left side upper rib. It feels like a knife is in it. I find myself applying pressure and trying to move the pain but it doesn't work. Has anyone got a clue what might help? It is extremely painful and so irritating it almost makes me nuts.

It's called Ms hug people with MS get it I do have this and it's scary when it happens sometimes I think I'm having heart attack

i get it, i hate it but er assures me over and over I'm not dying. pretty sure they hate me.
