You have had pains in the lower stomach area and I assume it is
located in the lower quadrants of the abdomen. You do mention
that you are on a high fiber diet and now you are having clear
now. I am not sure whether you had any kind of
blood work , X-rays , sonogram or CT-Scan .
Depending upon your age , these are necessary to have before
making a definitive diagnosis.
Your stool needs to be tested for hidden blood. If that is positive,
you may have to undergo Colonoscopy
to rule out colitis
I wish you well.
