But, conditions do change over time, and advice as to diving can vary from one physician to another (sometimes depending on how much they know about diving), so if it has been a long time since your initial workup, it may well be worth seeing someone again.
DAN, Diver's Alert Network, is an organization which deals extensively with diver medical issues, and they can provide you with the names of diving-savvy physicians in your area, even if you are not a DAN member.
