When I was initially diagnosed, it was 1.1 cm, then grew to 2.2 cm (prior to treatment). Per my last CT, it's back down to 1.1 cm and looked like it was collapsing and turning into scar tissue. Hoping the daily meds and Arikayce will deal it the 'death blow'.

There's someone on here who had multiple large cavities and participated in the Arikayce trial. She said it closed up all her cavities.
