OMG I have just read this post about the feeling of pressure on the windpipe. I have been taking 12mg of Iodine now for a couple of weeks and am experiencing hot flushes and sweats but the worst is the pressure in the centre of my chest and breathlessness like I can't get enough air! I have stopped taking the Iodine as it has me scared but if what you say is a normal reaction then this can explain what is happening? Should I start up again with the iodine? I have been scared I am having a heart attack or goodness knows what else but couldn't think why the Iodine could be causing it. Any advice would be greatly appreciated.
