Hello @lucynn, Welcome to Connect. I sometimes have a little pain in my ankles but think mine is just due to my age and some arthritis. I'm pretty sure you are not alone though and hopefully other members will share their experience and what they have found helps. Here is some information I found on the topic.

"Why does my ankle hurt and feel heavy?
The most common causes include injury, arthritis and normal wear and tear. Depending on the cause, you may feel pain or stiffness anywhere around the ankle. Your ankle may also swell, and you may not be able to put any weight on it. Usually, ankle pain gets better with rest, ice and over-the-counter pain medications." --- Ankle Pain: Common Causes & At-Home Remedies: https://my.clevelandclinic.org/health/symptoms/15295-ankle-pain

It's good that it doesn't affect your walking or balance. How long have you had the pain, did it just recently start?
