What's the treatment for infection on a drain site drain sitemucky still hasn't closed took swabs results not back yet, tummy sore underneath site?

Infection. You may want to wait for the culture result to come back and then follow up with your doctor, (if the patient does not look very sick). The recommended treatment will vary, depending on the location, size of the wound, amount and color of the drainage. ----> But if the patient looks very sick or with high fevers, go to the nearest emergency room.
