I agree with all the above with regard to hiding a condition, for all sorts of reasons just don't.
1.has anyone actually had any success in removing an OML for a chronic condition ?
If it is any help FYI I know of someone flying in the UK who has regained his Class one and is flying heavies following successful treatment for Ulcerative colitis: I'm not sure exactly what his treatment involved, and whether he was cured ( if that is possible- I'm not a medic) or whether he got his licence back because his condition was controlled to satisfaction of the AME.
