Recently I was experiencing some pretty bad chest pain. Not the heart attack kind but the kind that hurt when I breathed, strained, and moved certain ways. Doc says I have costochondritis, inflammation of the chest wall between the ribs and lungs. Said it could be RA related. Gave me a new anti inflammatory. Last night I was so exhausted and loopy from a pain med change and ending up sleeping on my left side the night thru. I woke up with my right rib cage and collar bone in tremendous pain. I'm not even going to go into how awful side sleeping is for my hip bursitis. Have any of you experienced these types of pain upon waking?
