When i cough it hurts in my lower abdomen and bladder?

Hmmm,...: The cough reflex causes the valsalva maneuver, which pushes pressure against the Abdomen/intestines and bladder area. Since you are getting pains, that area may be inflamed or infected, so best to see the Dr. for your symptoms to get properly diagnosed and treated, best wishes.

Abdominal pain: you should be evaluated for possible hernia of abdominal wall OR possible early sign of appendicitis or another area of lower intestine, or a possible bladder problem. If the pain gets more severe, this would be indication for you to avoid solid food until you get your econdition better evaluated.
