I constantly have head aches. i am 16 years old, and i admit i probably don't drink enough fluids but that has never caused me a problem in the pass. i have suffered with back problems before but they calmed down about 5 years ago. However over the past 4 or 5 months I've been receiving constant headaches and quiet often feel dizzy and tired even with lots of sleep. also, my pains in my back have started again. i take tablets for my head with help, but not very often. when i ovulate, these symptoms become a lot worse. the last time i went to the options they said i did not need to wear glasses so what could be he problem?
