I Purchased A Bottle Of What I Thought Was Daily

I purchased a bottle of what I thought was daily Liqui-Kelp iodine What I was given at the pharmacy was a bottle of iodine potassium. With out realizing what I got, I came home and squeezed 1 dropperful under my tongue, immediately I realized it was not what I had been using. It burned my mouth so badly like if I had eaten habanero chili pepper, my tongue swelled and I started to sweat profusely. I called the pharamacist and was told I had not used it properly , instead I was supposed to have rubbed 1 drop onto my hand and was told to drink a lot of water to flush it out. There was no instructions on the label , the only writing on the label was Lugol's Solution Iodine 5% Potassium iodine 10%. Today my tongue still feels a little bigger than usual, and I am having a bit of trouble with pronounciation of some words, under my tongue feels slimy and puffy and it hurts. I'm worried about what effects this will have on my other organs and my whole system. my e mail is YYYY@YYYY Thank you.
