After an ankle injury, my physical therapist recommended to purchase Resistance bands of different strengths and BOSU Ball from Amazon. Resistance training, balancing exercises, and Stretching.
That being said, I would try finding a sports medicine specialist or PT to guide you through these exercises to address the pain you’re experiencing. https://www.verywellhealth.com/ankle-exercises-a-complete-guide-2696480
