have a sore irritated throut. bad cough, coughing up some greenish stuff. lots of sinus drainage. bad taste in mouth. teeth hurt part of the time. little trouble breathing. face feels warm and flushed a lot of the time, but I don't have a tempreture. feel tired most of the time. almost feels like some kind of infection. I take methotrezate for systemic lupus. so getting concerned. had trouble for several weeks now.
