Suggest Treatment For Infection Due To Cold

I began to get a slight infection about 2 weeks ago, green phleghm, lethargy and a slight cough. After about 5-7 days this seemed to clear up and I was well for 3 days or so. Thinking I was ok I went out and drank moderately but 2 days after this (around 10 days after the initial onset) the symptoms came back worse. I have now had green nasal discarge and chest congestion for 5 days. Along with this I have had a headache or two, pink eye, swollen glands on the right side of my neck only. And probably the most odd symptom, a lump about the size of a pea at the very back of my top gum where the cheek and gum meet. This pain has eased slightly and hurt more in the morning or when pressed. I am a 20 year old female with a history of a pvlsa infection around 9 months ago.
