Hacking up blood clots, as disgusting as it seems, is fairly normal after radiation and chemo. I hacked up dead tissue for about a month post Tx. It takes a while for the sores and burns to heal. If his temperature goes up to 100.5 degrees or higher you should get him to an ER stat. If you have to go to the ER tell them immediately that he has a compromised immune system and unless they're dealing with a heart attack or something, they should expedite you through. I didn't have a PEG tube and often had elevated temperatures up to 100 degrees.

The yeast infections in the mouth (thrush) occur because a. lack of saliva and chemistry imbalance because of it and b. compromised immune system. It's unlikely that it's causing the problem you describe but thrush is dangerous in a compromised immune system and must be aggressively treated. It can be fatal if it goes systemic. I was on a maintenance dose of Diflucan for months.

Other opportunistic infections can occur as well so you must be very careful to keep the PEG site clean at all times. Don't shave with a razor, etc. Nicks and cuts can produce nasty infections. Wash your hands constantly with soap and water. The foaming (surfactant) action of the soap dislodges the bacteria and is as effective as anti-bacterial soap. Clean the skin around the PEG tube as directed by your doctor. It'll take months for the immune system to recover so you must be on your guard at all times.

We also disinfected the kitchen and bathroom as an additional precaution and I didn't do out in public for months. For disinfecting we used a 10 to 1 bleach solution as recommended by the CDC - (1 part bleach to 10 parts water)
