Hello. I've been having some strange, bothersome symptoms over the past few weeks, including fatigue so bad that I've never experienced a tiredness like this before, some vision issues including burning eyes, and feeling like m not seeing colors as brightly as I should be (I was diagnosed with having optic neuritis last year). I've also been having what I describe like "pin pricks" that feel like little needles sticking me that will randomly happen anywhere on my body-arms, legs, face, etc. I've also been feeling dizzy at times, which comes out of nowhere, and shaky arms/legs when I am walking or moving around. The most troubling symptom happened yesterday more gin when I woke up and felt like my arms and legs were "buzzing." Thats the best way I can describe it. Once that buzzing went away, a few hours later I started getting pins and needles sensations in my legs while driving to work. I'm kind of concerned about these symptoms as they hit out of nowhere, and can be gone just as quick...except the fatigue, which has been constant for a long while now. Do you have any ideas of what this may be? Should I be concerned?
