A few days ago i fell and busted my lip. now it hurts bad. can i speed the healing or alleviate the pain?

Recommend consult: To speed healing need to make sure wound is as optimal as possible (i.e. no stitching) and no sign of infection (particularly if hurting badly). Recommend consult with a doctor licensed in your area to sort this out. If there is no intervention they can do they will be able to advise on pain management options.

First: See an Oral Surgeon or go to a hospital ED or walk in clinic and see if you need stitches or other treatment. They will tell you how to alleviate the pain.
