trough another forum I have heard of copper problems. Apparently the liver can not cope. That guy has been going trough a proper metal detox program and is now still under the care of a toxicologist and still goes nowhere near a PD neuro. Dat scans apparently are are conclusive. Sorry to hear you are having a rude specialist. That is really no way of dealing with it. Hope you get answers soon and are on medication to help you along. In the meantime try some Meditation, mindfulness, tai chi, yoga, anything to help you relax a bit as stress only make symptoms worse, sadly.
