Thanks for your responses. So I was finally able to talk with the oncologist�s nurse yesterday about 2:30 and the oncologist was already gone for the day and he is always off Fridays so he wasn�t available. The nurse seemed to think he would defer to the dentist�s opinion. I did ask the oncologist�s nurse about the hyperbaric treatment again and she just told me to talk with the hyperbaric doctor again. I know my husband really did not like the hyperbaric treatment and he feels his hearing and vision have still not recovered fully. I tried to call hyperbaric doctor and he was also gone for the day. It is just really scary and my husband who is usually the calmer of us was also really pretty upset about the whole thing. He sees the dentist again on 8/2 and we are supposed to go away next weekend before then so it won�t be too much fun with this hanging over us. He just finished the last round of antibiotics on Monday, saw the dentist Monday and the dentist thought it looked better, and by yesterday, Thursday the infection was back and worse with the bleeding. We live on the Gulf Coast of MS ( I am previously from outside Buffalo, NY and my husband is from MO) with not a lot of specialists available here in any areas. We went to MD Anderson at the beginning for a second opinion and their dentist thought his teeth looked good at that time. Just hope we are doing everything we should to get rid of this infection at this point.
