Rib fracture: First, a patient with a simple rib fracture can go to work because the rib fracture is surrounded by intercostal muscles, so the fracture is relatively stable and will not be significantly displaced. Secondly, it is not possible to perform strenuous exercise at work because strenuous exercise may cause displacement of the fractured end and aggravate the condition. Third, be careful not to get cold, because after getting cold, the local blood circulation will slow down and the inflammatory metabolites will accumulate, leading to the aggravation of symptoms, and you can wear a rib fixation belt for protection, which can play the role of fixation and warmth, which can promote the healing of rib fracture. Fourth, you must drink more water at work and take oral anti-infective drugs, such as cephalosporins or penicillins, to effectively prevent intra-pulmonary infections. Because of the pain caused by coughing and gasping for air after a rib fracture, many people are afraid to cough, which leads to the accumulation of phlegm in the lungs and leads to lung infection, so you should drink more water and take oral anti-infective drugs.
