Tendon inflammation or irritation on the inside of the ankle
Do you have pain on the inside of your ankle, just behind the inside of the ankle or in the arch of your foot? If so, you may be experiencing irritation of a tendon on the inside of the ankle.
These symptoms usually develop gradually. For example, you may notice the pain when walking for long periods, climbing stairs, exercising or standing on your toes.

What is it?
On the inside of the ankle are tendons that support the lower leg and the foot. These tendons help to keep the arch of the foot and the ankle stable whilst walking and moving. The posterior tibial muscle plays an important role in this.
If this tendon is subjected to excessive strain, irritation may occur. This is often referred to as tendonitis. In many cases, it mainly involves tendon irritation or tendon strain.
