Let's put it this way: I'm an ex-Army Warrant Officer who's been a coach, captain and center for a B-ranked hockey team in the USHL for over 15 years now, I have hour-long cardio sessions 3 times a week in addition to weight-training on off days and I frequently run in 10k races for charity and community organizations. I haven't had an asthma attack in over 10 years and I present with ZERO symptoms of asthma and ZERO side-effects from the medication I take to manage it. My FEV1/FVC came back at 98% before strenuous exercise and 99% after 20 minutes running hard on a treadmill WITHOUT having used my management medication for 24 hours prior. I'm not a doctor, but my pulmonary doc said I'm fit as a fiddle and they just don't know anything about hyperbaric medicine and therefore are not qualified to make a decision about fitness to dive. I love how a scrawny dive instructor whose neck I could snap before he can say "Diver down!" wants to tell me I'm not fit to dive. I understand the docs not wanting to put themselves in the liability loop and if I were a doc I'd likely feel the same. But telling me I'm unfit to dive? Tell me to my face, it would take a lot of balls my friend.
Lighten up, Francis.
No one said you are unfit to dive. You're simply not yet medically cleared to dive; anger issues notwithstanding. (Which is too bad, because it's become abundantly clear that you'd be an absolute joy to have as a student.)
