<human>: I have acute bronchitis and am on antibiotics, expectorant, and antihistemene. Before diagnosis my fever was over 104. Now with medications has lowered to 101. However, today I have developed severe upper back pain. What does this mean? Thank you.
<bot>: Hello, Process of acute bronchitis preceded by either viral or bacterial infection leading to inflammation of bronchi causing formation of a lot of mucus. Due to infection you have got fever, but this may occur due to complications like pneumonia. Coughing a lot to expel out sputum causes upper back pain. So you need to consult a good physician for further evaluation. Before that go for blood examination- CBC, chest x-ray, sputum culture, lung function test. Continue your medication and take rest with good amount of water. Take care, bye.
