I have an URI. I have taken one Z-Pack with minimal relief of coughing, bronchial and nasal congestion. This has gone on for weeks. Now the glands in my neck are swollen. Years ago I took back-to-back Z-Packs for something similar and ended up in a TCU with C-Dif and nearly died. I was on TPN for a few days. I am terrified to go back to the doctor for more antibiotics. The recent Z-Pack was the 1st antibiotic I'd had in almost 15 years because I hadn't really needed one. But I have horrible memories of that stint in the hospital with C-Dif. I'm taking Mucinex and Nyquil to try to relieve symptoms, but still have productive cough of thick white mucous. It was yellow like egg yolk before the Z-Pack. I will eventually go to the doctor, but why are these glands swollen now?
