Re: continue iodine

I dont think we can clear this up for you. Decisions like this we have to make ourself. As; if I recommended something and it all went wrong, I would feel terrible.
But if it was me, I would probably paint the area with iodine.

When it comes to iodine; yes if you are young and relatively healthy, I dont think you need Iodine every day.
My kids have Iodine 3-4 times, every second week. Then I give them approx 50-100 mg in each go.

What you need in addition to that is selenium (scandinavia is really low!) -you are from Denmark?

Vitamin C, every day the rest of your life IMO. There are options when it comes to price; In UK they have a really good one that cost less than 1Dkr per capsule. Same with iodine, purchased at the right place (UK) it is not costly at all.
These 3 is the very bare minimum, IMO.

I would toss in some Magnesium, vit B and boron, as it would support the system even more. In Denmark supplements are expensive, but since you are in EU you have access to the European marked.
