almost done radiation on my face for sinus cancer. face is beet red and swollen. hair has fallin out . dont have any taste left but the worst is i have tongue ulcers that hurt so bad they gave me all kinds of meds for pain i just need to know when these will go away and if any one can tell me when taste buds come back have 11 more treatments left and boy do i just want to quit. the dr said my mouth sores and radiation burn to my mouth is because the radiation bounces off cavitys and burns inside of mouth. and help for the pain and info on taste buds please..
