Yes, exercise is a great thing. I do not have any swelling at all. I finished my four drops today an hour ago. No reactions from it yet. I never had any major reaction like rashes, dripping nose etc. May be because I use Dr. Clark's sodium-iodide. I also fell that my vitamin Bs & C, Selenium and Niacin are contributing to this, as well as salt.
I hope your knee is better, mine is almost normal.
