In the past 6 months or so I've experienced muscle twitching, occasional numbness (particularly while sleeping), muscle pain, brain fog (slow word recall and slurring of speech), balance trouble, and occasional and brief sensations of dizziness. I've also experienced fatigue throughout the day and no amount of sleep seems to help. I'm afraid of going to the doctor because although I've almost come to grips with the fact that I likely have MS, I'm worried about my parents knowing but before I make an appointment I was curious if the symptoms I'm exhibiting could be caused by anything other than Multiple Sclerosis (fibromyalgia, Lyme's disease, thyroid disorder, etc...).
