There are no home ultrasound units. There are two reasons for this. One reason is that only trained personnel should use ultrasound equipment. Used incorrectly, ultrasound could worsen symptoms or even damage the tissues of your body.
The second reason is that ultrasound is not meant to be a long-term fix for your symptoms. It is used early to improve circulation, ease muscle spasm, and speed healing. This helps as you start a therapy program to improve your strength, flexibility, and alignment. The exercises and pain management strategies you learn throughout therapy should be what helps you keep your condition under control.
