There are many reasons for painful pressure on the rib cage on the chest side, first of all, it is a fracture cause. Secondly, the pain may also be caused by osteitis or osteomyelitis. If the fracture is mild, it can be left untreated because the rib is wrapped with a periosteum both inside and outside and has the possibility to reset and fix itself. If the fracture is severe, if it does not affect normal breathing and cardiopulmonary function, it can be treated conservatively without incision, such as external fixation or manual reset braking and resting to make the fracture heal. If the fracture affects respiration or cardiopulmonary function, or in more severe cases, if the rib pierces the pleura or damages an organ, then an incision and internal fixation is required. In addition, local fractures may cause damage to local tissues, resulting in nerve and blood vessel damage, numbness, swelling, and in severe cases, severe pain. These conditions should be treated symptomatically with topical antibiotics to prevent infection. In case of pneumothorax, the pneumothorax should be resolved quickly to prevent more serious conditions. In the case of osteitis or osteomyelitis, the condition should be treated symptomatically with antibiotics to reduce inflammation and pain. If the condition is worse, surgery is also needed to clear the inflamed tissue.
