Krishna,

I'm afraid I don't know enough to answer your questions on the lymph nodes and didn't have radiation, so have no information on IMRT.

However, I'm sure Brian and others do know. You might re-post your questions on the "Currently in Treatment" board so folks there will see it. You could also try sending Brian (Hill) a private message. He is always very helpful and I'm sure could point you towards the information you need.

One thing I can comment on is the spitting up of blood. How long has it been since his surgery? I wouldn't think that would be caused by the neck dissection, but could be caused by the tongue not healing completely? I wouldn't think it should still be oozing now... About the tooth, I'm guessing the toothache might be related to trauma during the surgery. I know my Aunt had a tooth chipped badly during surgery. Perhaps your Dad's tooth was bumped or jarred in some way. I know my teeth hurt like heck, but it was because of the jaw split. I was lucky not to lose any teeth.

Best of luck to your father as he undergoes radiation and recovery.
