Agreed. I have the same problem it's hard to determine if my issues are radiation related or a recurrence (one of the pitfalls of having cancer :P constant wondering if the smallest thing is a recurrence. ) usually the measuring stick for me Is a two week wait - if it hasn't shown improvement or healed it's off to the dr. Wait the requested time - have the test done again and if it's still there see the ENT immediately! Hugs and good luck!
