After two years of testing for every possible other cause, my doctors have decided it is probable that taking high doses of vasopressin in the form of DDAVP or Desmopressin for the last 15 years has messed with my CNS and caused autonomic dysfunction and a central pain syndrome. The end result is extreme burning throughout my body, much difficulty walking, and a host of other problems. I have found much recent research that suggests they are correct, but the doctors around me have no clue how to deal with it. I have just now stopped taking the DDAVP. I would like to know if you think this is reversable and how it might be accomplished. So far the only thing that has helped my pain is lidoderm patches. They are awesome, but do not cover near enough of me. Thank you so very much for your time.
