I am a bit late on this thread . The easiest way of experiecing the internal tremor for me is to put my teeth very close together and they chatter . Not audibly but I can feel them . Two things produce this reaction in a normal person , cold and fear . FEAR L-dopa produces a relaxed feeling in me as well inproving my movement disfunction . I tried to just stop the L-dopa and I had to resume not for any movement disfunction but for the a pervasive feeling of dread . Are pwps also emotionaly handicapped ? COLD I was at one stage taking my temperature at regular intervals . It fluctuated violently but always below normal . Before Irealized this I went and bought anew thermometer thinking that my old one was broken because the mercury would not rise above 35.5 the first few days . PD seems to have made my temperature control bad . In summer any heat is a problem . I have tried to put my internal tremors in their overall PD symptom context . I only suffer occasionaly from resting tremor but I now realize that internal tremors are almost continous . peace Alastair ( [log in to unmask] )
