Celtic Soul, Maybe I'm in a time warp (or just overmedicated), but I could've sworn your post wasn't there when I responded to Alice's last post (April 6 at 3:13). Your advice is good, but I should point out that this is not a recurrent problem--the asthma is chronic; the laryngitis is episodic, very rare, and nearly always in conjunction with some virus.
The tips on breathing and vocal exercises in this thread are good. Vocal training has, indeed, helped me over the past few years avoid straining my voice even when I sing for hours in a given day. [Despite the aversion many folkies have to amplifiers and mics, I readily use them when I feel that the venue is one where I will probably strain my voice trying to be heard without one.] BR>It's precisely when all the warm-up and breathing exercises, hydration, zinc lozenges, nasal decongestants don't bring the voice back-even after several days of resting the focal folds--that's when it seems something's going on beyond simple vocal strain. [FWIW, as of yesterday, I now have an actual incipient sore throat and other body aches--for the first time since the bronchial problems began 2 1/2 weeks ago--, so I think I may be dealing with multiple viruses. The docs think so--and so there's no medicine to clear it up, of course! ]
Getting to see a vocal specialist, of course, can take many days or even weeks. Meanwhile, if you make your living with your voice [speaking or singing] and you don't get sick leave, this can be a big problem financially. This is why I'm interested in any information other singers have about dealing with "true laryngitis." Or about whether and how much you can use your voice while fighting virusus without doing long-term damage.
Alice, as to "...approach[ing] the search by talking to some professional singers who have had medical care for their voice...," I will, as soon as I feel it's ok to start talking on the phone again. Right now, 'talking' on line is easier on my vocal folds.
I really appreciate all the anecdotes, referrals, tips, etc., folks. Always good to know what other singers have done and would do.
P.S., Ciarili, N-o-o-o-o! Not give up CHOCOLATE!!
