OK everybody out there, it doesn't matter WHAT you have, I know JUST how you feel, because I feel EXACTLY the same way! I KNOW you've been diagnosed with MS and I haven't, but I can tell you with absolute certainty that

...the overheating problem is just menopause
...the pain is probably arthritis, we ALL have it at our age
...the fatigue is because you stayed up late, like me
...the bad balance is low sugar
...the cognitive stuff happens to EVERYBODY
...the muscle spasms are because you don't drink enough water
...the numbness and tingling is because you slept funny
...the pain around your torso is because your bra is too tight
...your eyes are blurry because none of us are getting any younger
...and I know what you mean about Walmart syndrome, it's that stupid music they play in the store
...and the white spots on your MRI is because the doctors are in cahoots with the big drug companies, and they just TELL you that stuff so they can get your money.
