Hi. I'm a 22 year old male, and for the past 2 months I've had a number of symptoms which haven't been able to be diagnosed and it's ruining my life. I can barely travel and spend my days in bed. I've got extreme lightheadedness (like there's a "fog" around my head and it only gets stronger with time) dizziness, headaches, neck pain and stiffness, tightness of the throat (like talking and eating are harder) along with a constant urge to clench my jaw. My vision has also been getting blurrier and I'm very sensitive to light and sound. Recently I've also developed ringing in my ears which won't go away.
The doctors haven't been able to find anything except for claiming it's "stress"... when all this happened, I was on summer holiday and relatively stress free, so I doubt that's how I developed these symptoms.
I'm not sure if this is the cause but 2-3 days prior to getting these symptoms, I noticed that while I was having sex I would develop excruciating head pain that got worse as I was getting closer to finishing. It was less noticeable in certain positions than others. Soon after, the lightheadedness came on and all the other symptoms came afterwards. Any help is much appreciated. Thanks.
