Sadly trampoline isn't alwasy allowed during rehab, you'll have to check on that advice. My oldest is slowly coming to the end of a 3 month rehab of a nasty achilles tear. She has only just been allowed to bounce on the tramp, as it is quite tough on the ankle structure.
Take you time, it is frustrating, but if you go back too soon, or push too hard it will slow down the progress you have made. Bars are your friend, and now you can run and jump, beam will be more fun. Explosive runs like you use for vault should be built up to.
Good luck, I totally get what you are going through!
