Hi-I have been bulimic for over 25 years. When I was in my 20's I binged and purged most days, several times a day. I remember having sharp stomach pain at times and feeling like my stomach lining was raw if that makes sense but it never hurt to keep food down. About a year ago I started to worry about the possible damage I may have caused my stomach and esophagus over the years even though I wasn't having any symptoms.
I decided that instead of worrying about the possibility of something being wrong I would get it checked out and get some peace of mind. I had a Gastrointerologist scope everything from my esophagus to my colon and everything ended up being fine. After my checkup I decided enough was enough and I had the doctor refer me to a counselor who specialized in Eating disorders. I am still seeing her and I am making slow but steady progress.
I would encourage you to see a doctor that you feel comfortable sharing your eating disorder history with. If they feel that you need to be scoped make sure they refer you to a gastrointerologist as they spend years being trained in these type of procedures. The procedure is painless and over before you know it.
I wish I could give you a more definite answer but for me just knowing what was or wasn't wrong was a relief and from there I was ready to say enough is enough and finally get into therapy with an ED Specialist.
I know you have the courage to seek help and you will feel much better addressing the problem. Please keep us updated on your situation.
