@pmm Great paper thanks, similar to one I paid for but better I think. My wife is in a similar situation, but she can't get past Radiculopathy or Neuropathy, even though 3 doctors have said it is PN and 3 podiatrists, Neurology is blaming it on anything else, latest is over sensitivity, Functinal Neurological Type disorder due to radiculopathy, but we have an expert in this at the hospital, so hopefully my wife will see him soon. Two years and getting worse, m-spike is stable but kappa free light chains rising slowly but steadily.
