I live in Missouri and it gets hot & humid here. I try to stay inside, cause if I go outside I start sweating terribly, I mean like I just got out of the shower and didn't dry. Is this part of the MS?

The cold is bad also, makes you stiff legged.

Yes affected by heat and humidity. Cooling towels are a good thing to use . My nuero has also told me when you need to cool down fast an Icee or Slushee.

I love the heat but cannot tolerate it or severe cold. I have to be in air conditioning

yes, the heat makes me so tired and makes my limbs feel heavy. I also get temporary tingling and brain fog.
