Pleurisy (Pleuritis): You are likely having pleurisy (pleuritis). Go see your doctor. Typical if this is all that it is, a prescription of nsaids like Ibuprofen will help take care of it. But you have to go and ensure there is nothing else that could be irritating the lining of your lungs like a collection, etc. This is likely unrelated to your chronic back pain.
