I am 22 years old and For about 5 days now I have been getting a 'hot spot' on my lower right leg(in the same place evrytime), they only last about 10 seconds and they are not hot to the touch. i get them about three times a day. They don't really hurt and there is no visible effects on my skin. I am not on meds but i do have alot of allergies. do you think it is some kind of allergy or could it be something like a pinched nerve?
