Do you mean HBOT? That is Hyperbaric Oxygen Therapy, which a friend of mine who has had PD for many many years swears by!! I want to try it but it is very pricey in NYC!

I have heard that O2 therapy helps with the symptoms a lot, It is expensive, however.

Hyperbaric therapy is use for healing wounds
Is great therapy

Has anyone had auditory hallucinations where you hear sounds that may not be real, except to you? And if you have, was it a particular med that seemed to cause them?
