Oh Maureen, of course this will make you worry. It would make me worry. I know too, that this is the nature of this disease. You never get over the worry. I would be very reassured by the recent clear scan though and do my best to put this on the back burner. This is what I did with Kris's recent mouth ulcer. It's hard, but you can do it.
