I am sorry to hear doctors think you are crazy, I think doctors just say that to make you stop. They do not treat parasites, it is a unspoken rule unless you are a child, then they will treat you.
There would be a public outrage if they did not treat children.
Until there is a public outrage, they will get by with not treating anyone.
You indicate you have a problem getting meds. I suggest you look at vet supplies, the compound is the same, the price is less expensive, and that will help when you need quantity. I do not disclose sources on a public blog.
...Right now I cant hear out of my right ear. (sorry, I lost my right ear in 1995)
It's been this way the last 13 or 14 days. (Roar like a jet engine?)
...Ive tried every ear drop at the store.
Invermectin may stop they guy until you can find a surgeon, dose 200 ucg/kg/day.
Deoxycycline is available from Hong Kong, you can dose ~ 100 mg for up to 60 days, but hopefully 30 days would help.
If the worm has a fungal infection there is not much you can do, I leaked green yellow red blood fluid for weeks from my dying ear.
Do not tell him about the Invermectin or the worm, have a audiology test, get the MRI, schedule surgery. Once they operate they are committed to remove the worm.
