When the tissue that connects the heel to the toes becomes inflamed, the sufferer will experience pain on the bottom of the heel. Left untreated, the ligaments can begin to tear, further complicating the problem. Plantar fasciitis can be caused by poor alignment or flat feet, but is usually caused by wearing incorrect shoes, particularly among athletes.
Treatment includes stretching, icing, shoe inserts, and anti-inflammatories. Extreme cases may require night splints or physical therapy.
