Can you crack your back after a compression fracture?

I broke my back like a month or so ago. It was a VERY mild fracture. I have low bone density, so I fell from like two feet and broke it. But anyways, I can walk and everything, the doctor said I don't need my back brace anymore, and it doesn't hurt anymore. Only when I try cracking it it hurts, which is annoying lol. How long should I wait? Will I be able to crack my back at all?
