Your plastic surgeon will always be your best resource when it comes to postoperative care questions. Some plastic surgeons have very strong opinions... If you do decide to use either modality of ice or heat, please be sure that you do not place them directly on the skin and potentially “burn” the skin, which may be numb.Best wishes.
You will need to provide more info about your situation in order to get a better answer to your question. I don't know anything about what you had done. Thanks.
