stomach tenderness 5 months post hysterectomy

hi i just wondered if anyone else had the same problem as me. I had total hysterectomy in january & in two places at each side of my navel i still have tenderness when i touch them, is this where my ovaries were? also my stomach is still swollen on one side more than the other- is this normal? i had an ultrasound a month ago but that didn't show anything so gp said it could be scar tissue but he didnt know what the tenderness was- its not getting any better, any help would be appreciated, thanks
