Indent in Chest After Gynecomastia Surgery, Why Would this Happen? (photo)

Hi doctors. Its me Jean again and i got a better picture to show what I believe to be a deformity (note I know its been too little time and changes might occur, but i am getting paranoid i saved an worked hard to have this operation.) P.S another two things i found at the top of my chest there is a hole and when i press on it, it sounds gushy i suspect fluids,but why would it dent?. And my right side when i flex the muscle there is a crater on the left of the nipple, please help.
