I recently added kelp to my list of supplements. I started taking it 3 days before the sinus problem started. I have read that iodine can chelate and since kelp has iodine in it....well could that have been what happened? I could have just over done it a little during the holidays but was very careful not to get too overloaded. Sinus infection is clearing up real well now. This one was different than most of the ones I have had in the past. I had major water works, runny nose ,eyes, lots of saliva...uggg. Also chapped lips and nose like never before. Anybody got any clues. Oh usually when I get sick it goes straight to my muscles, no coughing or sneezing but this time it took the usual route...no muscle pain at all. Maybe that is a plus? Thanks Guys I appreciate any info!
