I wanted to see if this should be a concern.
Are you pushing down to hear it squishing? If so, dont! Try and keep the area clean and exposed to air as much as possible. If you are worried and have worsening symptoms I would call the hospital to be on the safe side. Hope you are ok!
My son has a fluid build up the incision site that turned into a meningitis infection and he needed a revision. He also got really sick and high fever so get it checked just in case.
