I am a teenager whos never had any of these symptoms before. I started out with bad headaches but they dissappeared after a few days leaving only mild pressures once in a while, now I feel dizzy and weak all the time. Also have this weird sensation in my head, cold hands and feet, trembling and balance problems, which is mainly caused by that " weird" sensation. I am afraid I might have something serious going on, any suggestions?
Yes - see your doctor. He is the only person who can tell you if you have anything wrong with you. It's probably something minor but he can put your mind at rest.
Here is the best suggestion you will ever receive, go to the doctor. I'm sure you'll be alright I hope you have a good day.
