I have problems regulating my body temperature too. It seems I have a very narrow range of temperatures I am comfortable in. Too much either way and I am miserable. I think the heat is the worst though because the heat makes my heart rate go wild. At least in the cold I can put warmer clothes on…until I get too hot, lol.
It is funny you mention the tip of your nose, my husband teases me about it all the time too. Mostly the tip of my nose gets cold and he keeps telling me he is going to make me a “nose jacket”.
My hands get so hot that when I touch someone, it is uncomfortable for them. Most times I don’t know my hands are hot unless I put them together. I have noticed along the way that when I am feeling really bad, my hands are like this.
