The first thing you should do after a sprained ankle is get an x-ray to make sure you do not have a fracture. If you do have a fracture, then you must wait for the break to heal first and then have your doctor clear you for rehab.
Then, once your doctor lets you know you are ready, HEM will be extremely beneficial and integral in helping your ankle fully heal. HEM will help you regain lost strength, stability and healthy range of motion while also helping you eliminate any residual swelling and/or pain.
