Tonight, one of my characters, an aspiring smith was purposefully burnt with the tip of a steel blade fresh from a forge. (ie, another person held the tip to her cheek to teach her a lesson about sneaking around in other smiths' forges.) Due to monatary reasons, as well as her extreme stubborn streak, I don't see her visiting a healer for treatment.
What are some of the things I could reasonably expect to happen to her over the next few days in dealing with the burn, and how bad would the pain presumably be?
Also, in a psuedo medieval setting(Lord Of The Rings), what would be some of the options she could utilize for treating the injury on her own?
