I'm 17 years old and have recently been feeling tired even when I have a great night sleep. I can sleep for hours at night but then also have naps during the day just because I can't keep myself awake. I have only been like this for now 2 months. I also have been having headaches that can last up to 3-4 days, I will take medication for my headache but they do not work. The pain is usually the back of my head and sometimes above my eyes. I have also been getting chest pains now and then. They last to about 5-10 minutes each time. I just want someone to tell me if I am sick or should go see a doctor?! Or if you could tell me what you think is wrong with me? Someone please help?
