I turned my ankle over this morning coming into the office and it started to swell immediately. how do i tell the difference in a sprain or fracture?

Sprain: Usually pain is the indicator , but I have had fractures walk into my office . See your podiatrist for x rays and the help you need.

Ankle injury: A lot of the symptoms of sprain and fracture are similar involving pain, swelling, bruising and difficulty or inability to bear weight on the joint. The severity of the sprain may also make it difficult to distinguish from a fracture, and significant swelling can make it difficult to see a fracture on x-ray. If there is clear bony deformity or displacement a fracture is more likely.

X-ray: You will need and x-ray to see if you have a fracture or if it is just a sprain. Have it evaluated by your physician to get the appropriate treatment.
