The first goals of treatment for plantar fasciitis are rest and reduction of inflammation. Wearing comfortable shoes that have thick soles and rubber heels is recommended.

For athletes or performers who need immediate relief, an effective method is to administer the steroid dexamethasone using a procedure called iontophoresis, which introduces the drug into the foot's tissue using an electrical current. In extreme cases, so-called release surgery may be needed to relieve pressure on the nerves that are causing pain. It is nearly always very successful, although it requires a large incision and takes about two months to resume complete normal activity. Another investigative procedure called orthotripsy uses shock waves directed at the affected heel. Treatment for Bursitis.
