Hello, I had my takedown back in 2008 and in 2010 i had a simple procedure where my surgeon made the scar look thinner and smaller on my stomach. Ever since my takedown i had a bubble in the middle of my scar where i feel like there is no scar tissue underneath. It feels round and like there is a hole underneath my skin. Does anyone know why that could be there? It doesnt really bother me too much but it just feels weird and out of place.
