Wife said my legs were making a swimming motion when sleeping. does this sound like rls or plmd? i do never experience twitching awake. parkisons?

Need sleep study: Could be PLMD, but you may need a sleep study or polysomnography (PSG) to confirm the diagnosis. Follow up with your physician.

PLM: This sounds like periodic leg movements. This is certainly not Parkinsons. Restless legs syndrome is also different. Periodic leg movements are important only if it interferes with sleeping. http://my.clevelandclinic.org/disorders/periodic_limb_movement_disorder/hic_periodic_limb_movement_disorder.aspx
