Hi Lottie, its Michele and I had my HBO treatments and waited 3 weeks for surgery, the oral surgeons wanted to pull 5 teeth because in 5 yrs they would go bad I told him I just wanted the failed tooth that had the root canal and he said two other teeth are bad. I let him pull two back molars on the left side and one on the rt side and have been crying and regretting it ever since. I have only done 2 HBO treatment since the surgery was on a Friday and HBO started this past Monday and I an worried about infection, he told me to take antibiotics and I broke out with a rash, I am worried sick about infection and ORN I look at these big holes and hope I make it through this. I will be very pissed if I don't do well survived to operations from oral cancer and now this. Hope your husband does well. Let us know how your husband and you are doing, take care, Michele
