Also consider, as you have lost some weight; the goiter stayed the same size as before, just more visible as the rest of you is smaller. Neck, face and shoulders is about the first to show weight loss.
One month per year you have had the illness, is how long it takes to get well / cured if you have the right remedy. This is what my teachers told me at school. I found this to be pretty accurate.
As long as you feel good and things are improving on the iodine/glandulars I wouldnt worry to much. Maybe the swelling is there to stay for a while longer, same as with a calcified joint or inflamed tissue.
Acupuncture may help.
