I have had constant headaches and some eye irritation on my left side for a few years now. I have had just about every test possible. MRI's ENT doctors, and recently a spinal tap. Everything seem's to come back normal but I suffer from this everyday. I recently seen an eye specialist,(optic nerve is fine) ,plus a neurologist even been allergy tested and they find nothing. It is so easy to tell my symptoms because my right side is normal. Sometimes it's more intense than others but I get alot of pressure underneath my left eye. I also get some dizziness behind the eye. I hate to keep going to the doctor because of the way they are starting to treat and look at me. I recently started seeing a Chiropractor, and that has not seemed to help yet. I am extremely worried because it seem's to be getting worse. Can anyone please help ? Thanks.
