Replying to Spinal compression fracture

So I'm about two weeks into having a compression fracture in my lower spine (landed on my ass from a height) and after seeing a real doctor yesterday they confirmed my diagnosis and gave me a back brace. Its not one of those aluminum monster ones, but its still a metal cage on my torso. It's super uncomfortable on the chest (maybe because I don't have pectoral muscles but that's neither here nor there) and I doubt I can go 8 weeks with it. They tell me it's not a very bad fracture (20% height loss in the vertebra), so should I wear it? They said it's not necessary but I want to heal up quick
