Acl surgery question?

Just had acl surgery with the patellar graft. Im finally sleeping on my sides and what not but I can't walk much less stand up because the bruises are KILLER when I stand up and the blood rushes to my knee... this is 7 days after surgery. Does anyone have any tips on faster recovery.. better ROM and to take bruises down.. plus how to relieve pain after standing up?? Thanks :) btw... I didn't have any meniscus torn so it was just the graft.
