It's on the side of my lower left abdomen, and somewhat towards the lower left right of my back. It just happens out of the blue and if I try and take a deep breath while it's happening, the pain gets sharper. It last no more than fifteen seconds each time. -I did just get over a really bad, flu like, cold. Could that have something to do with this? At work, I could barely speak or move because the pain was so awful. Any ideas?
