I am a 48 year old female, quite solid and fit. After a short jog (15 minutes) for the 3rd time (new activity) and taking it an easy pace, 10minutes in I have been experiencing very excruciating low abdominal pain (womb area, deep dragging sensation) wanted to vomit and felt faint with the pain which only subsided whilst sitting on the shower floor with hot water flowing over stomach for 20 minutes. I am reasonably fit and exercise 3/4 times but shocked about how my body has reacted and think jogging is not for me! What could the problem be!
