Hi, this past Thursday, I noticed my left lymph node was starting to swell, its now Sunday and it is very swollen (almost 1 inch wide) painless to the touch, but since it got bigger, I feel a burny feeling when I move my head. I also have a very itchy rash on my arm, upper back and my eyelids, started on my arm about 2 months ago, then to my back and eyes. I do sweat at night, but not to where I wake up soaking, just sweating on my face and upper body. My lower back started aching yesterday (Saturday)Other then this I feel fine. Any help would be greatly appreciated. Thank you.
