For the past 2 days or so, I've had this weird burning and cold feeling in my legs and other areas. Like it will feel like my toes and feet are cold and when I feel them they actually will feel cold, and then not soon after I will feel a burning sensation there and in my leg. As embarrassing as it is to say this, I even feel this in my penis too. I don't know what this is but it is scaring me so much. I didn't do anything sexual I just started feeling lie this. I am a 15 year old male, so what could this be? Also when I urinate I sometimes feel a burning sensation. Any advice will be greatly appreciated, thank you.
