My rep. told me to be careful during the scarring in process as the scarring can be torn and have to reform. Unfortunately, at this point in order to get the relief I need in my lower back I have to put up with feeling it in my abdomen. My rep. called it the "band effect" and said that it may go away with time as things heal and he can tweak me...or it may just be something I have to get used to and live with. It's not bothersome other than feeling weird, so if I have to live with it to get the back pain covered, so be it.
