Yesterday, I was doing a few reasonably light pause deadlifts (beltless) for 10 reps at a weight I could possibly get an extra 2 or 3 reps out of, when I felt a small pop in my lower right rib area followed by a slightly painful sensation very similar to having a stitch. I was stupid enough to continue the set and finished off one more set straight after which obviously increased the pain.
Today it is still a bit tender whenever I take a deep breath, bend over to tie my shoe or just touching it. I can still train other movements just nothing which involves pulling off the floor and bracing my stomach.
I was curious as to what it might be, how long It might take to heal and what could have caused it so I can prevent it from happening again?
