Hi there!
I am so glad to have stumbled over your post just now!

I have been suffering of neuropathy for a few years now, and many factors such as mercury poisoning seem to have played a role, but the real pain started after I received traditional acupuncture at a Chinese practitioner. I had consulted her for nerve tingling in my feet. The first session was absolutely amazing and I felt wonderful after the treatment. The tragedy happened at the second session: the acupuncturist hit the radial nerve on my left lower arm. Already during treatment I felt my whole arm aching starting at the fingers, up the hand, creeping up, up, up infused with pain. I told her to stop, but she simply answered it is normal to experience a certain amount of pain during treatment and left the needle in.

The following day I had what I call an electric nerve shock experience: my whole peripheral nervous system reacted, burning, crippling pain creeping up my feet, legs, hand, arms. It took me a few days to recover a bit, but since that acupuncture treatment: not a single day without pain. 3 years now.

So, yes, I am certain acupuncture can damage nerves. I do not know about earwax vacuum treatments, but the ear is connected to some very sensitive cranial nerves. If damage happens there it could most certainly effect your whole nervous system.

I hope you find a way to cope with it. If you do, please let me know since none of the doctors here in Europe were able to help!
