I have been experiencing severe headaches on the right side of my head just above my ear for about the last three months now. I would have visited a doctor but have no medical insurance and no way to pay for a trip to the hospital, symptoms involved are normally confusion sensitivity to light and the feeling that I am the stupidest person in the world. I use to be quite able to express myself in words but now it sounds as if I am drunk all the time and I don't drink. Are these regular headaches or should I risk a trip for testing.
