The pain in my lower back area close to my left kidney or lower left lung, could have been caused by an abnormal twist movement this afternoon . could it be just a lung pleurisy ? caused by me twisting my long separating it from some lining ?

Left lower back pain: Pleurisy unlikely unless coughing,SOB, and have an URTI. Pleural separation is seen in pneumothorax or effusion and would be associated with more breathing issues, short of breath(SOB)- twisting is unlikely to cause it . If concerned can get a chest xray. Most likely just muscle strain from twisting for which warms soaks, NSAIDS if not allergic, can help. May also be stone. f/u/ w/ MD
