My husband had bypass surgery on his legs. i think his leg is infected. what should we do?

See your surgeon: It is pretty common to have an infection of the incisions after a lower extremity bypass. If the incision is red, tender and draining fluid it makes sense to see the surgeon sooner than later. Your husband may need antibiotics and should have the wound looked at to make sure there are no un-drained pockets of infection.

Seek help: Call surgeon or go to er immediately. The graft can become infected and need to be removed, in addition to the other problems with infection. Do not delay treatment!

Consider ID consult: First thing: follow everyone's advice here to go to your surgeon and seek help from them first. Second thing: an infectious diseases specialist may help your surgeon choose the most appropriate antibiotic available, and to consider potential complications that merit additional work-up or streamline diagnostics.
