I have suddenly started having Myoclonic seizures, could I be epileptic?

I am an 18 yo male. It started about a week ago. I stayed out all night with my girlfriend, and we had sex. After we were done, I got this feeling in my right leg like a continuous electrical current flowing right above my kneecap. That lasted maybe 20 seconds, and after that, my legs started to twitch a little bit. Not constantly, but like every 20-30 seconds they would twitch for a half a second. I walked into Walmart and it progressively got worse, my legs (mainly my right leg) started to get worse and do it harder and harder. I got back out to my car and I couldn t drive, because it was to the point where I was involuntarily kicking my leg. I had my girlfriend drive me to Urgent care and they took a blood lab. It came back inconclusive, so they had me get an MRI. The only thing they found was a small cyst on my pineal gland, they said that it is most likely not related to my current condition. So they are now having me go see a neurologist, I need to set up an appointment for that. But it moved from my legs to my abdomen after a couple days, and just yesterday to my neck. It is like my muscles engage or jerk anywhere from 0.5 seconds to 15 seconds. It doesn t feel like a normal twitch either, it feels like I m doing it but It s completely involuntary. Being physically relaxed or engaged doesn t change anything, but the quieter my brain is or the more focused I am, the less they happen. I am also motionless when I sleep. Could I be epileptic?
