Thyroid Enlarging on Lugol's?

Still waiting for test results from Dr. Brownstein, but now I swear my thyroid is more swollen since starting Lugol's a few months ago. I thought maybe it was my imagination since I wasn't aware of it till he palpated it and pointed it out, but yesterday I didn't take any, just kelp, and for a few days before that about a half dose. Today I took 5 drops in water, idea being to take another 3-5 drops later (it's 5%), and while I feel fine, I swear my thyroid is more prominent than it was this morning. I'm also getting itching on my neck at that spot (not from over-feeling it, I'm not constantly touching it or anything).

Has anyone else experienced this? Is it an early stage of cleansing and repair where it's likely to improve, or could this mean my dose is too high? Dr. Brownstein told me to continue what I was doing even though I mentioned that I felt more cold and tired on the Iodine (still do, but otherwise feel like it's helping some things, and it could just be the antimicrobial effect as the reason I feel better in general).

Really weird. I am 95% sure I'm not imagining this.
