Sawa, I tried accupuncture for six months. He treated me three times a week to the tune of $600 a month! It didn't help my fibro one bit but it did help my hearing! So there is something to this. I honestly don't know how accupuncture could help with a tear. But I'm definitely don't know a lot about accupuncture. You might want to give it a try again and see what happens but I wouldn't pin my hopes on it, personally, because you might have to have accupuncture all of the time to help with the pain and that is very costly.
