Hi there Belinda and Welcome to HealingWell!
Sometimes when you go down hard on a muscle (or group of) and they are tense, they can take a while to recover. If they are still sore in a by next weekend, you might consider seeing a doctor to see if you have torn anything rather than it just being bruising. As Carla has said, I know a fair bit about epilepsy. I am 22 (nearly 23) and have been diagnosed since being 15 ish. I have done a lot of research for myself and for others. If you have any questions you want answering, please feel free to ask.
All the best
Darren
