I got one after a intense detox and sun bathing.... I use 12:1 ratio of Olive Oil and Oregano Oil. I would then apply coconut oil before bed time. It lasted 3-5 days. One thing that seemed to work real well was to apply Sea Salt onto it.... I have heard the real dormant lies a parasite/worm somewhere near the spine. When I applied the salt it was a very intense pain on my lip. Followed by a interesting shock near the spinal region.... Seemed someone did not like that down there!!!
