I am a 25 year old female. I have a problem with my left eye. If I cover my right eye using only my left eye then it begins to go blank. My vision has always been 20/20 (although I haven t visited an optometrist in a couple years.) If I open only my left eye my vision is extremely spotty. I feel as though it may be getting worse. At night, I have been having problems with pulsatile tinnitus in the left ear (I researched this problem online and am purely assuming that s what the whooshing sound of blood in my ear drum is due to). I get slight headaches, am always fatigued, seem to have neck pain (am always straightening my posture to lessen the pain), and have extremely stiff neck ligaments connecting the muscle to bone on the front of my neck. I m most concerned about losing my vision. I m cutting gluten out of my diet in hopes of this all being a simple allergy that is causing inflammation and these problems. Has anyone had similar problems or have insight on what may be going on??
