What is wrong with me?

I have a mild headache in one side of my head and have had one for a few days now. sometimes my head will have a tickling sensation inside. just this night my whole body had the sensation. it almost felt good but somthing didnt feel right. when i lay down or stop moving i feel like i need to puke. i also have muscle spasms. im 13 years old. could this be puberty? Is this normal?
