My symptoms are left side more than three years and I'm left handed. Lately been noticing a little twitchiness in right hand at times, but not yet an actual tremor. I was a very active runner until a mysterious hitch developed which I described as my "left front end going out of alignment." Went to docs, chriopractors, massage therapists, etc., (no neurologist), and it was so subtle that no answer was found. Some suggested muscle imbalance, tight tendons or muscles, etc. No amount of stretching or strength building brought me back into "alignment." Now I understand it was early PK. Chuck
