Hi
It seems you are having hives with cold and physical stress/exercise acting as the trigger factor. Itchy red blotchy skin on exercise may be due to a condition called Exercise urticaria characterized by itching, or hives on the legs, arms, chest or neck during or after exercise. You should consult a doctor for a proper diagnosis.
Sometimes the symptoms may be related to the ingestion of certain foods before exercise, in which case you should stop eating it for some duration and see if the hives stop. Most symptoms can be controlled by taking certain antihistamines prior to exercise as prescribed by your doctor. Even then if symptoms start, you should either slow down or stop exercise. Very rarely your doctor may advise to avoid certain types of exercise.
Regards
Thany you for your follow up. I don't think my condition has to do with the kind of food that I eat because it varies a lot. What I am concerned about is when my body generally gets cold, the itching and hives begins.
Thank you
For the past year or so when my skin gets cold, it gets red and itchy but goes away when my skin is no longer cold. This happens when my arms are in the cold pool water or just walking with short sleeves and perhaps shorts when the temperature is 50 degrees or below. So, this is not related to exercise. I wonder if there could be any reaction to these supplements which I have been taking for years.
