Its frustrating that we don't know what EXACTLY is going on at a cellular level. We can distinctly see the difference in colour and texture between our ec affected areas and non-ec areas with the naked eye. And we get biopsies and they look at our lip under a microscope and tell us its normal. Frustrating. One year ago all I did was party and get laid. Now all I do is try and get my lips to freakin heal(sorry I know I sound like a pussy, but f***).
