A little over a year ago I started having headaches. they came on gradual and progress untill I had one constant headache.Plus at time I would get blurry wavy lines in my vision. an MRI was done and a pituitary tumar was found. I have seen several doctors and they all say that the tumar is not the cause on my headaches. I have been on several medications and nothing at this point seems to work. I sometimes get very bad migrains and need to go to the hospital for shots to help relieve the pain. Other times I get very sudden sharp intense pain to the left side of my head behind the eye. these pains will last from a few seconds to several minutes. i done done research and have found one thing that comes close to what i am feeling and that is cronic daily migrains. Also my research shows that the tumar can cause headaches. any information would be a great help
