Pain in left side after going to the loo.

In my childhood youth, I always had a thing about not wanting to go to
the loo. I would be in stitches & cramps, & I would cry all the time.
Not very pleasant. I don't know why I did that but I did.Fast forward
into my teens & now my adulthood - I have facial acne. I go to the loo
now & the more times, the better. However, I suffer that same slight
pain to the left of my stomach, just above my hip but more at the
front. It's a dull ache after a # 2. This area also feels relatively
weak regardless.Any info on the matter will be appreciated. Thanks.
