Usually this happens during a yawn. At the very bottom of my right ribs, underneath a sharp stabbing like pain, and the right of the neck, top of shoulder kinda also recieves a sharp pain. Both sharp pains last only a minute if that. I usually walk around and just wait for it to leave. Only happens when i yawn or deep breathe and lasts not even a minute. Happens maybe once or twice if that a day. but after the pain leaves im back to feeling absolutly fine again. have this issue for more than an year
