I am not sure why this posted to the anxiety community, my apologies for that.
The only way to find out is to see someone who can answer the question -- the appropriate specialist. Even a chiropractor or osteopath can probably answer it. But as someone who practiced ju jitsu as well as kung fu, I've had rib issues, and it certainly sounds like one.
If the rib is bruised or cracked it will heal by itself, but pain can continue for a long time. When I broke a rib it took almost a year to be completely free from pain.
ribs. do you smoke cigarettes ? your ribs are rubbing up against your side k
I injured a rib in high school. 30 some years later and it jumps up and bites me, just as the doctor said it would.
