In the last couple of years I've noticed that if I get cold, I sometimes get very itchy and break out in small hives. Sometimes just getting out of bed when the house is cold in the morning can set it off. I feel it mostly in my extremities, arms, feet, hands and legs but usually in just one area at the time. The other day I was out and wearing a skirt with bare legs. I suddenly started to itch so badly, I've left red marks on my legs from scratching. It usually passes after after about 15 minutes or so and I've noticed that if I take an anti histamine first thing in the morning, it's usually not a problem.
Has anyone else had this? A friend suggested it could be a symptom of peri menopause (I'm 47) but I've never heard of that before.
