[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Lower respiratory tract infection - pneumonia causes pleurisy. Pleurisy is Inflammation of pleura. And this can cause pleuritic type of pain. This pain is common in back side because pleura extend somewhat lower than lungs. So treatment of lung Infection should be the priority in such kind of back pain. Warm water pad application on affected area is also helpful. Painkiller and anti-inflammatory Chat Doctor.  So first control lung infection for your back pain. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
