Hi Michael,
So sorry to hear about the ringing. Sounds really miserable. I do have one idea for you. My husband has been going through hyperbaric oxygen therapy (HBOT) recently to heal a soft tissue injury at the BOT caused by the radiation treatment. I've been reading quite a bit about all the uses of HBOT, and there are many. I think the tech at the hospital told us there are 14 or 15 FDA approved indications now. At any rate, I did run across an article on HBOT and tinnitus which indicates that HBOT can help. I have this one URL which has several study results:
http://www.hbot4u.com/deafness.html This article seems pertinent, perhaps?
http://www.hbot4u.com/deafness1.html Here is another, though I didn't spot anything on tinnitus on it, it does have someone you can e-mail for information on HBOT:
http://miraclemountain.homestead.com/HBOTManual.html I know nothing about the legitimacy of either of these sites. It was something I found while googling. I can ask my husband to ask his HBOT doctor next week whether HBOT treats tinnitus.
Also, you might want to find an HBOT doctor there or where you live and find out for yourself whether this might help you.
P.S. It's quite expensive, and I'm sure the insurance would only cover it if tinnitus is one of the FDA approved indications for HBOT.
Good Luck,
Connie
PS... Here is something I found from the Integrative Medicine side of the house. (I don't know what acupuncture might have to offer in this area, though worth checking) :
