hello,
i had gallbladder surgery last april...things didn't go well. blood pressure dropped more than once. had to stop the surgery. anyway...i had a horrible time recovering and to this day there is a hard knot right above my incision on belly button. i have never been fat there, but it sticks out and i call it my alien baby. it still looks like i am pregnant!! any answers as to why, how to fix???

thanks in advance
