thanks for your post. i had tn surgery 8 weeks ago. upon going home i too noticed i was hoarse at times. i ignored it for a couple of weeks while i was recouperating. then when i went back to church and tried to sing i really had trouble singing. i was a soprano and each time the notes went up nothing came out. saw ent after several more weeks while the voice problems continued. the dr quickly did a procedure where he ran a small tube down through my nose to view my vocal cords and had me do a few notes. the procedure was not unpleasant.he showed me on a monitor afterwards and said i had a varicose on my cord and said some other stuff too. said the surgery was long and the tube did damage. dr said to rest my voice (no talking) for a week and set me up with speech therapy.he said i could sing again but that my soprano was gone and to move to the alto section. he wrote in the chart my voice had a raspiness quality. also thought i may have a nodule farther then he could see. time will tell. if your voice problems continue see an ent. and don't wait too long.
