Yesterday I noticed a little sharp pain in my appendix area but I thought it was because I was jogging. Today it got really painful and I couldn't walk properly or when I laugh my stomach cramps up just above where the pain is. I doubt it's appendicitis because I don't have any of the other symptoms apart from a sore throat. When I press into it I can feel a small bump and it's a bit swollen around it. Can somebody please tell me what it might be? Thanks!
