Ashley, yes once we have had a run in with this disease we always worry.
Unfortunately anything is possible with this disease too. You have done the right thing in getting your ENT to check it out. Hope your CT is scheduled soon and that it turns out to be nothing. Better to be safe. I know this is worrying, but worrying won't change what is.
Let us know how you get on.
