After the leg infection and pus, you need to go to the hand and foot surgery department of the hospital promptly, flush the wound with hydrogen peroxide and saline, disinfect with iodophor and then cut and drain the wound to drain the pus. Then place drainage strips and change the medication regularly, every day or two days to observe the changes in the wound, and after the pus is drained, you need to change the medication regularly to promote wound healing. Infection and pus in the leg are mostly caused by infectious diseases or trauma, resulting in slow local blood circulation. If suppuration occurs, abscesses need to be incised and drained, along with the application of antibacterial drugs, such as cephalosporins. However, it is important not to drink alcohol while taking cephalosporins to avoid disulfiram reaction. Pay attention to less activity and more rest in the near future, and pay attention to a light diet, eat more coarse fiber food, and then eat less spicy, stimulating, greasy food, etc.
