I think the trick for you now is to rest it untill it's pain free when doing normal (light) daily activities and then go through a rehab programme from there otherwise you ruin your training too, this in turn may jepodise future fights. Also, get the elbow checked for any laxity problems that may come about from the injury.

See a good sport/physio therapist will help in this situation, as sports therapy in the UK an unregulated industry (unlike physio) get a university qualified one.
