I have a pain in my stomach on the left side about 3 inches left and 3 inches below my navel.  About a week ago I did some ab workout, but I noticed the pain yesterday.  It occurs on certain movements (like when I turn over in bed).  Is this just a muscle strain?
Hello! Welcome to Chat Doctor, Since you feel the pain only in certain movements, most likely it is caused from muscle strain. If the pain was a symptom of specific abdominal condition, you would feel it all the time not only in certain movements. If the pain doesn't seem to get better in 1 week or get worse you might need to consult a physician and get examined. Right now it doesn't seem something serious. Hope it helps. Kind Chat Doctor.
