"I have been using this medicine for about 6 months. I had 1 toenail on each foot affected. It causes swelling in my ankles and knee.  I have seen an improvement on my left foot but not that much on my right, but I used it for the same amount of time. It is swelling my feet too much. I will be stopping the use of it today. My doctor wanted me to hang in there with it. But I can not walk with this product. I switched to putting it on at night, I thought that would help the swelling but it has not. Too difficult to walk with the swelling."
