I have had this problems for six years now. Except the last year has really been bad. I have severe headaches, lightheadedness, chest pain. I always feel like I'm just going to drop anytime now. It's really scary. I have seen 3 neurologists, a neurosurgeon, ent, cardiologist, lyme doc, accupuncturist, eye doctor, dentist, and numerous internal doctors. Noone can give me a diagnosis or medicine that will help this. I cannot drive due to it and stay in the bed most of the time. The lightheadedness is 24/7. I have a lot of pressure in my head all of the time. The tests I've had include, 2 brain mris, brain angiogram, emg, nerve conduction tests, ct scan of brain, ct of chest, gallbladder ultrasound, eye exam, dental exam, cardio workup including catherization, etc. This is constantly getting worse. Oddly enough, they will not do a spinal tap, even though one doctor mentioned pressure in my fluid could be causing this. I'm pushing for the spinal to check, but still cannot get anyone to do this. I'm 36, female, obese, with 3 kids and a husband and no insurance. I cannot excercise due to this, because I feel like I'm going to fall any minute. Ms has been ruled out. The lyme doctor said probable lyme, but wasn't sure. Could it be a pseudo tumor cerebri? That's what I'm thinking. Any advice would be appreciated.
