Some night i believe i'm having partial seizure only night time is that possible only right arm and both legs at night &some days i just twitch?

Could well be : Obviously, varying events could occur at night including seizure activity but also movements associated with a sleep disorder. Not a bad idea to sort this out, via an overnight sleep study, to ascertain the value of modifying your meds.

Yes: Some people only have seizures at night. The pattern of one arm and then both legs is.is consistent with a seizure pattern. Consult a neurologist and have s sleep deprived EEG. Sleep deprivation and drowsiness may bring out electrical seizure discharges.if that EEG is I revealing,an ambulatory EEG recording for 24 or more hours, hopefully will capture an episode for diagnosis.
