What should I do if my leg itches when it is cold?

Western medicine mainly treats skin pruritus by calming and relieving itching.

If the skin is dry and itchy, remember not to scratch the affected area, so as not to scratch more and more, which will expand the scope. Maybe everyone has had this experience. Sometimes walking from a cold outdoor to a warm indoor, or taking off a thick coat and lying on the bed before going to bed at night, the skin will suddenly itch under the stimulation of one cold and one hot, and you can't help scratching, but often the more you scratch, the more itchy you scratch, forming a vicious circle.

When there are common itching symptoms, you can take sitamin and cetirizine without sedation during the day, and take chlorpheniramine, cyproheptadine and other antihistamines with sedation half an hour before going to bed at night.

Suggestion: If the whole body itches, you can take anti-allergic drugs such as aminophenol or cyproheptadine to relieve the symptoms.
