Yesterday I started to feel a sharp pain that lasts less than a second. It's coming from the same location as my appendix. It comes and goes. For example, last night at work I think I felt it six or seven times. I don't have any of the symptoms of appendicitis. I have had pains in this area before but nothing this sharp. I'm going to fast and flush my colon ( Oxypowder & salt water flush) just to be on the safe side.
