Hi. I am actually a teenager who suspect that I have skin allergy. Whenever I am exposed to cold weather or cold water, my skin will become red and I could feel a burning sensation. Sometimes, my skin will also become itchy and swelling occurs.
Also, I have fainted after swimming in a cold water environment. Not only that, I feel that I am going to faint even if I exercise in a warm environment (i.e jogging on the treadmill). At first, I thought that my low-blood pressure causes it. However, I read in the internet that the reason that I could faint (or feel that I am going to faint) is connected to my skin condition. Is it true?
If so, can you advice me what should be done? Thanks.
