I live in Moldova, and recently went to a doctor. He recommended IV ozone. I have researched and it appears to be very effective and is used extensively in Germany. The clinic here charges 200 Moldovan lei (about $20) for a one hour IV treatment and recommend a minimum of two weeks. The equipment was imported from Germany and from my past experience with doctors and treatments here I am very impressed.. so I will start next week and see how it does.
