question: I am 43 years old, and about 2-3 months ago started having pain and swelling in the right side of my back. Gradually over time, I have started having pain and swelling in my joints. Yesterday evening my neck swelled up on the right side, with one very large lymph node. I have noticed all my lymph nodes are swollen somewhat, but especially the back, neck and shoulder on the right side. I have within the past 2 months taken a zpack, acyclovir for shingles, and now another zpack. I have blood work pending. Any idea why I would have so many lymph nodes swollen for so long? Just started running a fever last night.
