Yes, the infectious disease specialist should be helpful. I would also suggest seeking out a wound care specialist. The treatment facility your husband goes to should be able to help you with finding these specialists. Hopefully they will be affiliated with his facility and work together with his current team of doctors. There's all kinds of different things available to wound care specialists to help to heal stubborn wounds. Patients who have had rads have compromised healing capabilities around the field of radiation. I feel so bad for your husband, hes been thru so much already!

After the complications from my mandibulectoy, I had a "tunnel" open wound about 6" long that ran along my cheekbone to behind my ear. It was comparable in size to a 6" long piece of cooked spaghetti noodle. No matter what my doctors did, this sore just refused to heal. I was referred to a wound care physician. After about a month they suggested I also see an infectious disease doctor. I saw the wound care team 2 or 3 times a week and the infectious disease specialist about once a week. Every so often the wound care staff would take a swab of the wound and send it off to the lab to see what type of sore they were treating. The wound care office was located across the street from the infectious disease doctors office. About every other week, the infectious disease doctor would pop in during my wound care appointment and check on my progress. It took a long time, about 9 months but the wound finally closed. I ended up doing 8 months of very strong antibiotics 3 times a day thru a picc line along with HBO and with the wound care team's special treatments it all came together and closed the stubborn "tunnel".

Hope this info helps you. Best wishes with everything!!!
