I was seen at the Dellon Lab in Townsend, MD. Dr Dellon did not take anything but $, so I was given one of his assistants. The procedure only took away my money, but my pain is so much worse 6 years later. No alcohol, taking b12, ALA, Turmeric and Methadone Without the Methadone, I could not walk at all! They give you their sham testing device and of course they said they could fix me. I shelled out the $ that i somehow got my insurance to pay a bit. It may work for large fiber impingement therapy, but not for small fiber PN. I felt I was used and taken by a group of MD's who went to Johns-Hopkins, I will never just base my decision on the hospital they went to for their medical school. I would be in a wheelchair if I could not take the Methadone. All the other meds, such as Amytriptiline, Neurotin, Lyrica did NOTHING. I hate to take Opioids, but i have no choice. My thoughts are to stay away from them unless you definitely have Large Fiber Impingement syndrome and most surgeons can take care of that, ie. Carpal Tunnel procedures.
