hello, im only 20 so im not too worried, however this has happened maybe twice in the last month. i feel a weird feeling in my arm, i cant recall which exactly, but to mee it seems like it would be the artery. it felt like a slight pressure, or tingling feeling and i know its not normal. again i am 20, but i have diabetes and i am a heavy smoker, so this may be related to blood pressure, im not sure.
