I guess this is what you would call it but it's really really bad!
I've never suffered from anything like this before, but it's been on and off for months now. It flares up, to the point that my lips are bleeding, and the skin around my lips is actually stingy and painful - and then I just wake up one morning and it's gone.
I've been monitoring it and I think it's stress related, but there's not much I can do about that for now. In the meantime, is there anything other than vaseline that might help - it's becoming unbearable. ☹️
