<s>[INST] I ve been pretty much in bed since Thursday - low grade fever on and off, very tired, heavy head. Went to dr Friday, they did a flu test which was negative. They said it s a virus that should clear up in a few days. I also have bronchiectasis whicChatDoctorpromises my immune system . Low grade fever now, first had it last Wednesday night. [/INST] Hello, i can understand your concern. Symptoms like fever, feeling tired, body aches all suggest a viral infection. While testing a flu, we usually do not do tests for each and every strain. So even if the flu test turns negative it can be a due to a new strain. Any viral fever would take a week time to recover fully. Donor pain if you have mild fever, body aches. It would clear on its own. Take paracetamol for fever and a multi vitamin tablet. Chat Doctor.  </s>
