Use Vaseline and peel them. That's the only way. But that will just make the condition worse.
I waited 2-3 months before I started seeing progress. And I was as careful as humanly possible. Based on what you have been talking about kissing, etc I can guarantee I was more careful with my lips than you. And it took close to 3 months to see progress. And I had only had EC for less than a year. So my inflammation wasn't as bad as most others.
When your lips have this severe inflammation for this extended period of time, it will take a long time to get rid of.
You people just have to be patient. Or give up. Whatever floats your boat.
