Inflammation is the body's natural response to injury & infection. Some people have claimed that their EC was cured just from removing their mercury/thimerosal teeth fillings which apparently was causing an allergic reaction.
All of my EC biopsies have returned showing hyperkeratosis. So, something within my body is causing this reaction. Some people have identified the spleen to be directly tied to the lips in some way. I went to a doctor who actually told me that there might be an issue with my spleen. I stopped going to him when he began trying wacky ass treatments that not even he knew how to properly administer.
