What is used to heal Anterior Ankle Impingement? Already have done rest, ice, ankle exercises, and NSAIDs with no results after 5 months.

Impingement. Many times non-healing ankle impingement is caused by a boney structure... if that is the case it will not get better until that piece of bone is removed.
Surgery. is an option if you have failed conservative measures and have had the appropriate diagnostic measures such as MRI/ultrasound. This may be an arthroscopic or open procedure to debride and excise the tissue or bone responsible .
