I've had plantar fasciitis for 3 yrs in both feet and have tried everything, is there a cure?

No: While there is no reliable cure for recalcitrant plantar fasciitis there are surgical procedures including gastronemius recession (strayer type procedure) which offer the hope of curing this aggravating condition.

ESWT, Surgery: Last resort treatments for plantar fasciitis would include shock wave therapy or eswt. Surgical intervention in the form of a plantar fascial release also can be effective but requires more healing time.

ESWT.: If you've tried supportive shoes, inserts, icing, stretching, and oral antiinflammatories for 6-8 weeks straight, you may need cortisone injections or physical therapy. Check in your area to see if eswt (sound wave therapy) is available, and in rare cases some people do require surgery.
