I drive about 40km to school/work and back every day. It sometimes takes me quite awhile to be able to get out of the car and then be able to totter off (and I mean totter). Stiff ankles and heels (never knew that could be a thing) and pain in the coccyx from sitting. I struggle with the tailbone when sitting down for too long at any time. I'm on a different AI (Letrozole) and it has impacted joints, and I suspect, soft tissue around them. It has also brought on arthritis in my fingers and neck in an amazingly short time.
