Did I have a seizure? I woke up shaking uncontrollably and could barely walk [22M]

Title. I (22M, 5’9 165) actually made a post on Reddit last night because I have been feeling weird symptoms for a while, I’ll leave that here: https://www.reddit.com/r/askneurology/s/egmlYgG40t But essentially I’ve been experiencing neck numbness and pain in my temple area for a couple weeks now, and have thrown up each of the last couple mornings. Last night I felt really numb. After drifting asleep, I felt myself jolt awake and twitch for a few seconds, but eventually I fell back asleep. I woke up 2 hours later to what I described in the title. I also had bed marks across my entire left side of my body, like I had been struggling in my sleep. The left side of my head also felt off. Went to the ER, they ran some blood tests, said it came back clear then just sent me on my way. My condition did improve throughout the morning and while waiting in the ER. Anybody have any advice on what I could be experiencing? The ER said they ruled out anything serious but I feel like this is a big deal
