Sometimes, the plantar fascia does not heal. After several months, more aggressive treatments are undertaken. One is the injection of steroid medication into the painful area to relieve the pain temporarily. Other options include ultrasonic tissue repair in which a needle-like probe is guided through ultrasound imaging into the injured tissue. The probe tip rapidly vibrates to break up the damaged tissue. The tissue remnants are then suctioned out. A last-resort treatment is a surgery to detach the plantar fascia from the heel bone.
