There has been a report of pulmonary barotrauma from as shallow as 4 feet. And if one is symptomatic with asthma, one doesn't know whether there are any small airways which are all but blocked.
Can I say the OP WILL have a problem if he dives? No, and that's why I recommended the PFTs. But I had an experience with a student who had much milder asthma than reported, and when his PFTs were reviewed by the folks at Duke, he was advised not to dive.
All diving involves risk assessment, but some risks are higher than others.
