See a doctor: It is difficult to tell over the internet. Bending over and having abrupt onset of pain may mean you are simply having a muscle spasm or a more severe condition such as another compression fracture. It is best to see a healthcare professional asap for a proper evaluation.

Compression Fracture: Particularly with known vertebral disease, acute pain can be a worrisome sign. If you have any numbness, tingling or weakness or bowel or bladder dysfunction these are very serious signs that require immediate evaluation. Your vertebral column houses your spinal cord and pain may signal a problem that can compromise your spinal cord.
