Thank you for posting that you may get more sore before getting better. I slowly worked my way up to 50 mg Iodine a day and suddenly i am more sore than before i began. I'm 57 so it is not a cycle thing. My dr. Said the cysts rarely go away and yes they will asperate them if you let them. I too have heard that is not good to have done. Started researching on my own and came across the Iodine info all over the internet. Not one dr. Has ever even mentioned it to me. So i have done it on my own. I stopped at 50 mg only because that seemed the most common amount for fbd. The soreness surprised me but i am seeing ithat can happen. I do notice one side seems lighter so i've got some stubborn cysts. My mammo a year ago said both breasts had scattered cysts in each one. Just wish they would GO away.
