PLANTAR FASCITIS: Treated early in the cycle, plantar fascitis can resolve rapidly. When a person has had it a year or more, the treatment cycle is longer. Regardless, the most overlooked aspect of plantar fascitis is nerve dysfunction of the motor nerves of the sacrum which control the calf and foot muscles. When the nerves are irritated, the muscles tighten and have less capacity to contract, so the fascia is the last defense. It stretches causing fasciitis and pain. To correct it, the nerves and muscles must work properly to hold the foot arches up. Sometimes arch inserts or orthotics are needed.
