Hey, I'm a student too, and I've been dealing with this for.. 8 months now. Al I can say is rest. You'll of course want to keep up with your studies, naturally. But, you will not benefit yourself from going in all of the time.

Try to see a neurologist or psychologist who can write a letter, informing your school/college about your injury, this could give you 'considerate marking' and extra time in exams. This I found very helpful. Most importantly, do try to stay off when you feel rough, and try to do keep up with your work but a more suitable pace for you.

I was stupid - I carried on and didn't take time off for a long time - my exam results in January reflected that. I don't want someone else to be as silly as I was.

All the best and good luck
