Mine is on my left side about two or three inches under my rib cage. When I lay down though it sort of goes to the side and I can't have fills laying down. Mine actually has dropped since surgery and my surgeon said not to worry that sometimes they do. As we lose weight the skin weight from the tummy will pull down on our muscle is how I understood it. I'm ok with where it is but sometimes when laying on my stomach it's annoying. It's all part of the deal.
