If the pain is in the same location when you strain or cough
try to place your hand over that area and see if you feel any
lump or bulge. You can also lean forward when you try this.
If you are able to feel something , it is possible that you
might have caused a hernia
. Especially, if you already had
a small defect in the lining of the abdominal wall, you could
have aggravated it by pulling a heavy object.
If the problem continues, you might want to have a medical
check up by a doctor or a nurse practitioner.
Wish you well.
