Pain in the lower abdomen can be associated with constipation
build up of gas in the intestine that can put pressure on the nerve
endings. You said that you did have results after taking senokot.
It is possible that the evacuation may not be complete. You might
want to take stool softener
like Surfak or Doxidan once a day for a few
days. Main thing is, your dietary habits.
I recommend that you go on a high fiber diet which includes whole
grain cereal. fresh fruits and vegetables along with adequate amounts
of water. Also regular excercise program, like walking 2-3 miles/day
three times a week will be helpful.
Any kind of infection of the intestine usually causes dirrhea and even fever
. In your case that is unlikely.
Sometimes, laxative tablet itself can irritate the lining and give some aches
Hope this helps.
I wish you well.
