Islandborn,
If you haven't visited these two sites, then spend a lot of time there and get familiar with what you think you have.
MENIERES.ORG -- Coping support site for Meniere's Disease. You are not alone!
Otoneurology Index
I've spent several years thinking that this is what I have, but there is no real diagnosis for it. It's a long process of elimination much like trying to diagnose the disease fibromyalgia. I have constant tinnitus and often suffer from nausea/slight dizziness when I lean over, rotate my head, etc. I've been to the best ENT in my area and have had many many tests, but he can't say I have it for sure.
If all you are experiencing is tinnitus, then you are a long way off from having full blown Menieres. Rotational vertigo is very pronounced in those who truly have the disease, and it is very debilitating. I have never had this, but I do feel nauseated (car sick) most days and both of my ears ring constantly.
I realize we are on a weed forum, but I can't say that I've received any ear related medicinal benefits from smoked cannibus or tincture. The only thing that helps me with the nausea (not the tinnitus) is a 0.5 mg. tab of clonazepam. It will not address the tinnitis. I don't think there is any cure for that. But if your ear problem causes you to become nauseas, then clonazepam will truly help. Good luck!
