Hi, i moved to a cold weather place 6 months back. I have noticed that whenever i get nervous, or cycle or get into a place where there are room heaters turned on, i develop body itching,burning sensation and redness and sometimes small bumps.But this lasts only for few minutes and then i am normal. I never experienced this in my home country where it has tropical and hot climate. But i am experiencing this in this cold weather place for past 2-3 months.What could be the reason and treatment?
