Thank you for your question.
The person you really need to be asking is your surgeon. Every doctor has different pre and post operative protocols for their patients. Some doctors provide you compressions garments while others require you to purchase it yourself. I would invest in a BBL pillow to take pressure off the buttocks when sitting, along with some ice packs to help relieve the swelling. It may also be beneficial to buy some protein shakes or meal replacements because they are quick and easy to make and you may not be up to preparing food for yourself the first few days after surgery but its important to consume enough protein to aid in your recovery. Best of luck in your recovery.
