Done a rib/maybe a muscle under my rib when squatting

This wasnt even on my heavy set of squats it was at the end of my workout and i was squatting 80 kilos to see how many reps i could do i was upto my 23 rep i think and when i went down i suddenly felt a sharp pain in my lower right rib so i stopped , Im not sure if it is the rib or a muscle slightly under/behind the rib. It doesnt hurt now at all unless i put pressure on it or have a big stretch, however i havent trained in 1 week . Anyone else experienced this, if so what did you do

Might be a rib cartilage. Dave is the guru.

Can't do much around the rib area. Rest it up, and see how you go over the next week. Doesn't sound overly serious. I wouldn't be squatting or doing anything strenuous just yet. Hard to e-diagnose.

Edit: At a guess, most likely a muscle related issue (intercostal) in which case you can't do much about it apart from rest.

I did some squats before in my shed got up to 100 kilos when i went down the bottom it still hurts a little.
