Does anyone else have fairly good physical health but at random times have a random, sharp pain in a random location in your body? I will have this happen from time to time, and months can go by without anything happening. Then, out of nowhere, not linked to anything, I'll have a pain that lasts for a couple of minutes, eases off, and disappears. I have always found this very odd, because there is no pattern I can discern, and nothing I can seemingly link it to.
