local irritation and sensitivity and tendinitis. In the surrounding soft tissue are the neurovascular bundles. Local pressure can produce nerve irritation and neuritis. Finally deep to this are the structures of bone and joint. Local bone spurs and degenerative arthritis can cause focal tenderness, but this would also most commonly occur with activity. I would suggest that if symptoms become increasingly worse to include involvement in activity or increasing pain you would be best served having evaluation by medical provider. If it is found that this is being impacted by a singular shoe or a certain style of shoe then these should be avoided.
Thank you and have a great day.
