Mine went away for quite a while after working outside and also having to take large doses of L-lysine to stop having fever blisters from working outside. I'm not sure if it was the lysine or vitamin D from sun or combined, it went away but is back now. I left the seasonal job at the end of last year. I'm going to try taking lysine & vitamin D supplements as well as coconut oil with paleo diet in case of candida/yeast. Thanks for sharing.
