Jolting, shock, zaps help

Hello! I couldn’t figure out where else this should go.

But for the past 2 week, I have had this weird feeling in my body. It is like a jolting feeling, like when you almost fall asleep but then wake up. I don’t know how else to explain it.

It happens around 3-4 times a day. When I wake up, midday, evening and before I fall asleep. I’ll be going to the doctor in a few days, but I was curious if any of you perhaps knew what this could be, to help me calm down.

Thank you!
