Just finished hearing the hour with the Prolotherapy MD here in L.A. and all the call in people in various types of pain. One woman called in with PN and he went thru the was it from diabetes, alcoholism, she said NO. Then she went on to say something about she thinks it was from an anesthesia, I think that's what I heard. She's been thru all the conventional MD's and tests and gabapenten and he went on to say for her to get a SpectraCell vitamin/mineral etc test....and to make sure she is taking antioxidants. OPC's are powerful antioxidants. With my OPC's I take, I still take about 1500mg Vit C daily. This person was hardly familiar with alternative medicine. The Prolo MD is very much in that mode.
