Hi, I m 15 years old and in the past couple of years I ve noticed that my legs get red blotches when i stand for more than 5 minutes. It s a lot faster in heat, but it even happens in the cold. I also feel a lot of uncomfortable pressure in my legs, and have fainted multiple times. After researching, I ve just discovered POTS, and I show most of the symptoms. I was wondering if i should be concerned or if it s no big deal.
