<s>[INST] I have been sick today is the sixth day. I have quite a rattle in my chest, with some wheezing. I am coughing up green. My headaches on and off but the body aches have stopped. My throat was sore but now only hurts when I cough. Have had low grade fever but I dont now. Should I go to the doctor? Or will this resolve on its own? [/INST] Hello dear, thanks for your question on Chat Doctor. In my opinion you should consult pulmonologist and get done1. Clinical examination of respiratory system. 2. Chest x-ray. 3. PUT (pulmonary function test). Green mucus, wheezing and rattling sound, is more suggestive of either lung infection (pneumonia) or bronchitis. So chest x-ray is needed to rule out pneumonia. PFT is needed to rule out bronchitis. You may need inhaled bronchodilators and antibiotics. So better to consult pulmonologist and first diagnose yourself and then start appropriate treatment. </s>
