Take it from me.. DONT play guitar, or use it! bandage it up(with the stretchy stuff) firm, but NOT to tight!
DONT take tablets with booz.. and..
put a bag of frozen peas on your bandage (not directly on your skin) once a day for about 20min (thats all)
Then.. REST... REST... REST!! (most important!!)
Beleive me its the fastest way to get it repaired!
