Hi all, Quick medical question. I have searched but not found anything specific. I have Eustachian Tube Disorder, which for those who don't know, means my ears can't equalise pressure at the usual rate, so I have to do this myself or they pop quite painfully. I have full control over it now. I've always wondered, would this stop me joining up? I also want to skydive/parachute at some point. I want to join as an engineer (Not submariner) so I wouldn't have thought so, but thought I'd ask. I also USED to have asthma as a child and joint problems in my late teens because I used to be clinically obese, would this preclude me from joining? I also have had Hep B vaccinations due to possible exposure at work, this wouldn't cause any problems would it? (Hepatitis is mentioned on the medical notes, but in terms of actually having the disease) Cheers.
