In many cases pain in the foot and ankle area is due to chronic inflammation caused by an injury or trauma. Physical therapies such as therapeutic ultrasound could be very effective in relieving pain and reducing swelling in such cases. Ultrasound therapy leads to an increase in the blood flow to the area which can result in increased heeling rates, tissue relaxation and scar tissue breakdown. To achieve these, you may need a course of treatment. During the initial assessment, your podiatrist will carry out a thorough assessment to ensure that there are no contraindications and will discuss the process with you.
