OK, not exactly PAIN, but an uncomfortable "yawning" feeling in my stomach (abdominal area). Almost like hunger pain, but believe me I'm not hungry! Ever since I was a kid I had to cram a pillow to my side, or pile one on top of belly if I slept on my back. Most comfortable was sleeping on stomach but can't maintain that position very long. This weird "empty" feeling has gotten worse in the dottage of my 50's. The other night I came up with a theory. ALL the muscles in my body are very tight and toned...except for abs (life is so creul). Maybe this area where I have little muscle tone feels too "loose" by comparison. I would settle for that theory (and commence sit-ups), but my father has a similar and even more severe issue. He is 85 and more fit than I; he actually DOES 100 sit-ups per day. He has night-time stomach PAIN and has all his life also. He has to get up and walk around a few times a night until it settles. When we were growing up Dad was told he had ulcers and he attempted to control condition with diet (this was before ABX treatment). The ulcer theory has been disproven by doctors since then, but he still has the pain...and ONLY at night like myself. Does this sound familiar to anyone? It has always vexed me, and after an especially uncomfortable night, thought I'd throw it out there.
