I need some advice. I was doing STS today and was rolling down to do chest with dumpbells and I heard a popping noise and felt something in my waist. Like rib cage area. I think I might have popped a rib out. I was wondering if anybody has done this and if so what did you do for it. I can feel it to walk, bend over and breath in. I feel like I just need to crack it. Thanks for any input.
