Since being dx with MS 8 years ago, I have always had trouble feeling temperatures on my left arm/hand. I have burnt myself countless times and never felt anything until 1/2 hour to an hour later. The other day, I burnt my right hand and never felt it. I only discovered the burn later that evening when putting lotion on my hands after my shower. Even then I didn't feel anything, just saw the burn. I was rather surprised as I haven't had that happen on the right side as of yet.
I do have trouble with both my hands with water temperature. Obviously, I don't notice it when doing dishes, but I certainly notice it when taking a shower. I will put my hand in and the temperature seems just fine until I get in the shower and the water hits the rest of my body.

I have learned that if it feels warm to my hand it is probably a little too hot for the rest of my body and need to turn up the cold water.
Oddly, water or ice can feel so cold to me - like down to the bone cold. This includes tap water. I seem to be overly sensitive to cold water and not sensitive enough to hot water.
I know this subject has come up before but I thought it would be good to start another discussion. Also, what are some tips or tricks you have learned to gauge water temperature.
