I have an international student living with me so his English is somewhat limited. He complains of heaviness in his chest, no pain with deep inhalation, headache when he is supine. His temperature is normal, pulse is elevated to 92 bpm, respiratory rate is normal. Earlier today he was extremely fatigued and spent most of the day sleeping. He said he had chills and fever earlier this afternoon but not currently. no cough or sore throat. My question is, should I take him to ER or wait til the morning for an urgent care clinic and is there anything I can give him to make him more comfortable? Any ideas what could be going on with him?
