I had a tummy tuck over a year ago and in the healing process, I kept getting seroma. After having it drained 4 or 5 times, I finally had a drain put back in. Got that drain removed and then it still felt like something was inside there. The PS told me that its just the way my body healed. But It just doesnt seem right to have to have this hard ball feeling in my stomach right over my bladder for the rest of my life. It has the feeling of a 1st trimester pregnancy.
