Wow..I was beginning to think I was the only one .I have heard "we can't find anything wrong" so many times I could scream.But the pain still persists ...Sore spots in the ribs .Pain when I bend over to just tie my shoes even .The pain goes around to my back as well .Muscle spasms whenI turn wrong and having to sleep with a pillow under my ribs just to get any sleep at all..Then told its probably just inflamation in my ribcage..JUST...It has been a # of years since this started and it just gets worse each year...It did start as a result of physical exercise..First time it happened I was doing sit ups.A muscle spasm hit me and I thought I was having a heart attack ..Dr. said I probably just pulled a muscle.The Dr. says I should do exercises but there is too much pain when I exert it feels like something tying in knots...I was glad to see your question .Maybe it has helped me answer at least what the problem may be even if no answers for what will make it go away .Thanks
