New type of seizure

For the past week I have been waking up at 2am with severe body aches that keep me from returning to sleep. I have been taking 800mg of ibuprofen to resolve the aches. Last night, I awoke with the aches, took the ibuprofen and returned to bed. About 15 minutes later I started to feel a tingling sensation in both legs, starting above the knees. The sensation worked its way up to my head in about 5-10 seconds. From there, I can recall my left leg start to thrash about and my throat/nasal system was very rapidly making loud snorting sounds. I tried to speak to my wife (sleeping next to me) but I could not get any words out. I do not know how long this lasted. I woke up at 7am  with this recollection of what happened.
