Question: I am a 47 yo female with some spinal arthritis that I have had for about a decade. No other health issue. I am 5'5" and weigh 120 pounds. I had sex for the first time in three years and about an hour after, I bent over at the waist and experience the sharpest upper abdominal pain ever. No nausea, sweating, or heart palpitations. I curled up in a ball and the pain subsided. A recent gyn check up was, as usual, normal. Periods normal. We did have quite a good time and I had an especially good time. It reminded me of a sharp all over abdominal pain I had after a new Power Pilates exercise, except that pain was duller and presented the following morning when I tried to straighten up. Could that have been muscular? Could it be mechanical or chemical (oxytocin?). My back is no more uncomfortable than usual. I elevated my HR again by running up and down the stairs just to make sure my heart was ok..no pain...no shortness of breath. But it did make my abdominal wall feel mildly sore. It is not tender to press on it.
