I have been having these problems pressure in my head and at times it seems to need to blow up and it would feel better. I also ended up with high bloodpressure and thought it was that Dr. has thought migrains Depression meds just to see if it helps eyes blurr up and vision seems to be getting worse.I just feel awful all the time. Have not been diagnosed with anything yet just trying to learn to live with it. Is this ptc and what have you learned,I only read your problems and only found this sight today. I would not want a shunt or half way fix with meds that don,t work what does.
