Then about an half an hour later, I started sweating and I got  one extremely big headache. Now 6 days have passed and my back still hurts. I cant run at all or Il suffer from extreme pain.
Hello, Welcome at Chat Doctor. I have read complete details of your question. It looks from your details that you had a history of fall & having pain at your back & head. If this pain is still persisting & of severe nature then this can be a fracture. You should not ignore & should have an x-ray of concerned part. Till then, you should do following- -Take complete bed rest. -Avoid lifting heavy weight. -Take a good analgesic like Advil or sleeve. -Take a supplement of calcium & vitamin C. Hope this all will help you. With best wishes.
