Pain in the ribs isn't unusual at all. Often it's caused by coughing. I'd suggest that you get checked out by your doc to be sure there isn't something more that can be done and to be sure that you're doing the right thing by using heat and to be sure that it's really your ribs that are hurting and not something else.

try a chriropractor mine takes x rays 1st and then fixes you right up love him, he works wonders

Found out my bad pain ribs had popped out of place. Doc put right one back, left one still to painful to touch. Heating pad.

I get rib pain but it says that I’ have pneumonia

I do get rib pain especially when coughing I also use heat bags
