Painful Respirations: Pleurodynia or pain in the pleural lining, is often due to inflammation of the lining of the inside of the chest wall or surface of the lung. These two surfaces abut or touch one another with respirations and create localized pain. Often due to old trauma or viral infection, the condition can come and go. Usually rest and brief use of an anti-inflammatory help; an exam is often helpful.

Pleurisy: this type of pain with breathing is usually caused by a muscle strain between the ribs tho sometimes a rib can get slightly "out of place" - they usually pop back in hours to days. If severe, or lasting longer than a couple days, or if you feel short of breath now, see a doctor today. Otherwise, some docs and phys therapists can offer manipulation that can help this.
