Have a swollen lymph node in my neck.?

I have had it for about 6 months, it is on my right side of my neck like 2 inches below my jaw, and probably as hard as bouncy ball with a little ease. When it first appeared i went to the doctor. The doctor said it was caused by acne on my chin that had got infected.

When it first appeared i went to the doctor. The doctor said it was caused by acne on my chin that had got infected. So i had to take antibiotics it went down but never truly went away. About 3 day ago i got more acne on my chin and it is swollen again and even more then the first time. I'm not sure if that is what is causing it to swell. I have heard other people say that they wake up sweaty, and i sometimes wake up pretty sweaty to, i don't know if that is another symptom also.
Anyone have anything similar?
Thanks
