Started out with chilis, fever, then stuffy nose, sore throat, dry cough, and green/yellow mucus, 7days now&throat hurts worse and more coughing, go to doc?

Cold/flu ? If sore throat is worst they ( dr.) may check it for streptococcus and give you an antibiotic and or xylocaine gel to anesthetize it. Cepacol lozenges . Otherwise, supportive otc meds (mucinex (guaifenesin) dm for cough etc), gales salt & water.
Seven Days Sore. At seven days, it is time to see your primary healthcare provider. Less than seven days, likely a virus, supportive symptomatic care with tylenol (acetaminophen) or Motrin is all that's needed. An oral decongestant may help with the stuffy nose. Colored drainage longer than seven days may signal it's time for an antibiotic to treat a possible sinus infection.
