Ok this is going to sound insane I know, but 2 days ago I sneezed and experienced an excruciating pain on my right hand side around my rib area . It was kinda like a stabbing pain, and now I get it whenever I sneeze, cough or even inhale too deeply when I yawn. I'm guessing it's muscular because when I push on the bottom of my ribcage it's uncomfortable but not painful as such. Anyone else had this happen to them?
