When is the Pain going to Stop?

I'm annoyed that I'm still in pain at 13 days past surgery.  Why is there still pain?  Any one have a clue?

The pain is worse in the afternoon.  The pain is mainly on the right side where hardly anything was done except to put in an incision from what I know right now.  Why does the pain radiate down from the naval incision to deep inside my womb?

Any one have a clue?
