i have a history of migraines but nothing like this. they are completely different and only last a day or two. this has lasted over two months and got better for about 4 or 5 days after having a spinal tap. and now is better again after having a nother spinal tap. when it started i lost vision in right eye for 3 days after having a strange warm feeling run down the back of my head. ct normal. mri showed a 1.4 cm pineal cyst but otherwise normal. no pain meds or migraine meds have helped. demeral shots only help for few hours while sleeping then headache returns. LP pressure was 200 the first time and 16 the second whatever that means. does anyone have any idea of what is causing my headache, that at times causes screaming pain. when not screaming, it is constant almost like my brain is pressing on my skull and throbbs when i change position.
