Brief Answer: Cold injury Detailed Answer: Hi again Since the lesion is localized only to your one hand and the area is colder than normal, so you seem to have developed chilblains. As you know, these lesions tend to develop on exposure to excess cold air or water. They tend to be extremely itchy in nature. All you need to do is to keep the area covered and protect it from cold. If the skin lesion is very itchy or painful, you can apply a topical steroid cream like cortisone over it two to three times a day. Intake of oral antihistamines like benadryl also help to bring down the associated reaction early. Hope it helps Dr Geetika Paul
