Hi. I'm a 14 year old girl wondering about something.
I have an red ''pimple'' on my left shoulder. It wasn't there when I woke up today, but it is there now. It is half an centimeter in diameter, and the area around it, is warm and red. I wouldn't bother if was only a pimple, but it's hurting. My whole arm feels like I've just taken a syringe: the arm feels a little bit num, and if I try moving it, the ''pimple'' and the area around it hurts. My arm feels slack and it's like it's tired (even though I haven't done anything today, just relaxing).
My fingers on my left hand also moves slightly slower than those on my right arm if I'm trying to move them fast.
(I'm sorry if I didn't write everything correct, but english is not my mother tongue).
Please help me. I'm worried.
