Hello, yesterday I had a tiny bump on the back of my neck. To better locate the place, it is a part of the hair on the far left, at the very bottom (when I put my little finger behind my earlobe, I place my hand with my fingers together, my index finger is in place). The bulge is very painful to the touch, even without it. The pain wakes me up. I originally thought I had hit myself somewhere, now I see it on an enlarged node. Because of school and work, I can't get to the doctor in her ord. hours, so please for some advice, I have before the exam and I need to sleep in peace. Thank you.
