I have no idea what to say with regards to your other condition, though yes the chemo might be an issue to your immune system. Perhaps the 6 smaller doses as opposed to 3 large, or Erbitux since it isn't a true chemo... someone here more familiar with it may have a better grasp of what it does to the immune system. Also work to improve your immune system now. Diet is primary as you likely know. Best of luck, welcome and do get HPV tested. take care.
