I would go back to the doctor and request an x-ray incase they missed something and state to them that you are In pain and can't be going on like this
Occasionally x-rays can miss fractures, so if I were you, I'd request an MRI of the area. Also, you don't state your age, but if you have any osteoporosis or Diabetes going on, it could have worsened since the initial injury. Please go to your MD and ask for another evaluation of the area, and tell him that you want an MRI because you KNOW x-rays can miss seeing hairline fractures. In the interim, you can help it out by elevating it and staying off it when possible. If pain becomes too much to bear, you can use ice packs or hot packs to the area, and take an anti-inflammatory medicine that's over the counter, like Ibuprofen/Advil or Alleve. Good luck!
