Back pain that occurs with lying down and breathing usually refers to inflammation of the lungs or pleurisy, or it may be caused by fasciitis of the chest and back. If the pain is caused by pleurisy, it will increase with the pain of breathing. If the pain is caused by fasciitis of the chest and back, it is likely to be accompanied by pain in the front or back, which will be relieved with proper rest. If the pain is severe, you can take oral meloxicam or ibuprofen to relieve the pain, and you can also treat the back with baking electricity, massage, acupuncture, moxibustion, etc., and you can usually get a complete recovery in about 5-7 days. Such symptoms are likely to recur after exertion, so you should avoid exertion and work with your chest in your life, and go to the hospital for further examination if necessary.
