Most doctors recommend an initial six- to eight-week program of conservative treatment, including:
If this conservative treatment does not help, your doctor may recommend that you wear a night splint for six to eight weeks. While you sleep, the night splint will keep your foot in a neutral or slightly flexed (bent) position to help maintain the normal stretch of the plantar fascia and heel cord.
If the night splint doesn't work, your doctor may inject corticosteroid medication into the painful area or place your foot in a short leg cast for one to three months.
Shock wave therapy, in which focused sound energy is applied to the sore heel, may be recommended for plantar fasciitis. The shock waves are intended to irritate or injure the plantar fascia to promote healing. The overall benefit of this approach is uncertain. Other therapies that have been tried include radiation therapy and botulinum toxin injections. But their effectiveness is unclear.
If all else fails, your doctor may suggest surgery. But this is rare, and surgery is not always successful.
