Hello…I had a hernia operation 2 years ago, it was a very serious procedure due to my weight, I had to have 8 surgeries in one summer..i did not heal well and had a big open wound..for several months i went through the surgeries and i had to use a wound vac for the deep wound. The plastic surgeon closed out the wound and now it's 2 years later and i have gained the weight back and now i feel a bulge in my lower abdomen area. Could this be scar tissue from all the surgeries? Thank you so much.
