The past couple of days I've constantly had a horrible lip (that'll happen to me sometimes, but day after day of a bad lip is unusual for me). Today I've figured out a potential reason. The past couple of days I've started using mouthwash in the morning (it used to be just at night), and I realized that mouthwash might have a numbing affect (like oragel). I don't know for sure if this is the problem. Would you guys recommend I stop the mouthwash or do you think this isn't the cause of this problem? By the way, I've also had a pretty good sized crack in my lip (on the inside), but it's almost healed and was quite a bit worse 1-2 weeks ago, but I had a really good lip then. I don't think this could be the problem, it really hasn't seemed to affect my playing.
