• I need help with my swollen lymph node?

I have a swollen lymph node on the left side of my neck. I was sick about 2 months ago and was given antibiotics and I felt pretty good after a few days on the antibiotics but did finish them up (z pack I believe). No signs of my sinus infection, but my left lymph node is still swollen and I’m very tired. Not sure what to do now, as stated I felt better after I finished my z pack but very tired and still a swollen lymph node going on 2 months. I missed all the holiday gatherings because I’m so tired. I really was debating going to the ER, since I can’t get a appointment at my doctors for a couple weeks because they don’t count this as urgent. I haven’t felt like this before and missing the family gatherings at the holidays was stressful. I just don’t have the energy to do anything. Any suggestions or thoughts?
