There are more reasons for the painful bronchial pain, as follows: firstly, it is considered to be caused by respiratory muscle spasm, which mainly appears during strenuous exercise, and after rest, or after adjusting the breathing rhythm, the abdominal pain can be relieved by itself. Secondly, it is considered to be caused by pneumothorax or intercostal neuritis, which needs to be determined by chest CT and X-ray examination. If the chest pain is caused by pneumothorax, it can be relieved by appropriate bed rest, and if it cannot be relieved, closed drainage can be considered for treatment. If the pain is caused by intercostal neuritis, it can be treated with non-steroidal anti-inflammatory and pain-relieving drugs and nerve-nourishing drugs. Non-steroidal anti-inflammatory and analgesic drugs, commonly used are aspirin, pautazone, diclofenac, ibuprofen, etc., and nerve-nourishing drugs commonly used are vitamin B1, vitamin B12, methylcobalamin, etc. Then, consider that it is caused by abdominal organ lesions, such as cholecystitis, gallstones, etc. You can do abdominal ultrasound and routine blood tests to determine. If it is caused by gallstones, the need for stone extraction surgery can be considered according to the size of the stones.
