Pain in sacral area post fall on sept 1....should i have an xray? and if it is fx, what can be done about it?

Xray if hurting: An xray will tell you if you have a fracture. If you have a fracture, you will know that you're in for a prolonged period of recovery (with pain). Appropriate analgesics can be prescribed once a diagnosis that justifies their use has been made.

Talk to your doctor: You should be examined first. If there is a suspicion of a sacral (or lower lumbar vertebral) fracture, MRI is the test of choice. If confirmed, those may be treated with a cement injection, called sacroplasty or vertebroplasty.
