I would adjust with selenium until the sensation of swelling goes away. Throat pain was always a sign for me to back up the iodine, in the beginning. Later I found out about the selenium. Up to 800 mcg for a short time like a few days up to a couple of weeks.
For the phlegm, you need to give it time to heal. 6 -10 grams of ascorbic acid in divided doses througout the day should help.
