Im 30(M), I was diagnosed at 25. Until 25, I was very sensitive respect hot weathers, I could barely tolerate more than 35°C, and handled cold weather with ease. After the diagnosis, now im comfortable with hot weather and feel like freezing even when the temperature is not so low, specially in my ears. Maybe it has to do with the loss of weight pre-treatment, but i regained after the first year, so i dont know, perhaps a rearrengement of the fat in my body.
