I got a cold the last week of October. I had cold symptoms for weeks, I was well for about a week, then I started with severe nasal congestion, headaches, ear pressure. I went to Urgent care December 14. I was told I had a lingering sinus infection and that my Blood pressure was extremely high, At that time I already had a non-stop heachache for 2 days. I took antibiotics for 7 days. 3 days after my last antibiotic pill, A large lump appeared on right side of my neck. I went to ER and was told its a result of antibiotic, that lump should go away in 2 weeks. Yesterday, I woke up with another neck lump, this one on my left side of neck and I woke up coughing up some phlem and I am still somewhat congested. I am confused....what have I contracted?
