I would VERY DEFINITELY get in touch with your surgeon ASAP. I know that if I had developed something like that, that my surgeon would have had me covered. Depending on where the scar tissue is, it may not even be much of a surgical problem if the underlying tissue is in good shape. The sooner you do it though, the very much better. At four months you are still pretty much in the initial healing phase, so if you need help, give the doctor you just spoke to permission to speak to your surgeon and describe it colleague to colleague. I had it happen with a simple yeast infection, two doctors helping me.
