I have had that happen many times,.Usally at night before bed.I told my doctor he recommended more streching pd exercises on a regular basis.It has helped alot.
Last summer though i was very active,going down to my boat and going fishing with my dog .Tasha.
I hardly had much concern for PD.LOLBest RX for PD is keep moving and stay postive and enjoy life by helping others but with balence.
I have a good time Ive asked others but few takers ,people today are so nervous they cant stand being out on the water very long.
I would give it a day or two unless something drastic changes,stay calm and avoid self diagnosiing.
Hope you feel better
