<s>[INST] 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. [/INST] Hi, there is nothing much to worry with this. Sometimes what you read on internet is all about the symptoms, but the clinical correlation is always a very different. Why don't you try doing some regular aerobic exercises and then see. You can even look for specific lower limb strengthening as well. Workout for your core stability as well. All together this should take away your most of the symptoms, and you will find it ease soon wish you an early recovery. Thank you </s>
