A sprained ankle may be due to twisting your foot due to stepping off a curb, or stepping on uneven ground.  It is usually due to an acute traumatic event, and you usually remember it.  You will see your ankle swell up, you will feel pain, and you will also see black and blue bruising on the skin.  In the absence of these, your ankle pain may not be due to an ankle sprain but may be due to something chronic, such as arthritis or a chip fracture, and not due to acute trauma.  If your ankle is in pain it is important to see a foot and ankle specialist to get it checked out.  Our doctors at PPFAC will do a thorough history, lower extremity exam, and take digital x rays here in the office.  So if you think you may have a sprained ankle, contact our office and have it checked.
