Is the tugging sensation normal after tummy tuck? (photos)

I posted earlier this year about this. I had a tummy tuck a little over two years ago, and I still have that tugging, twitching, sensation at my belly button. It's really not a good feeling. I have to wear something compressed against it to not feel the sensation. I visited my PS a few months, and he said he didn't know what it could be, and that he didn't know what else he could do. I am at a point where I don't know what else my options could be.
