[|Human|] I am 69 and taking sulfamethoxazole 2 times daily for bronchitis. Last 3 nights I have had a fever and chills during the night. Am still rather weak and lack energy and have difficulty breathing. I had heart bypass in 2002 and my lungs aren t good because I smoked many years before heart attack and no not smoke since 2002
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Fever with chills in bronchitis patients are suggestive of lung infection like pneumonia. Since you had heavy smoking habit in the past and now suffering from bronchitis, your lungs are weak and prone for infection. So we should rule out pneumonia first. So consult pulmonologist and get done 1. Clinical examination of respiratory system2. Chest x-ray 3. Complete blood count. Chest x-ray is must for the diagnosis of pneumonia. CBC is needed to know the rise in total white cell count. You will mostly improve with broad spectrum antibiotic like levofloxacin or Azithromycin. So consult pulmonologist and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
