Heel pain isn't normal

Plantar fasciitis is the term commonly used to refer to heel and arch pain traced to an inflammation on the bottom of the foot. More specifically, plantar fasciitis is an inflammation of the connective tissue, called plantar fascia, that stretches from the base of the toes, across the arch of the foot, to the point at which it inserts into the heel bone. Overpronation is the most common cause of plantar fasciitis. As the foot rolls inward excessively when walking, it flattens the foot, lengthens the arch, and puts added tension on the plantar fascia. Over time, this causes inflammation. Dr. Adam Brown of Carolina Foot Specialists in Charleston, SC explains in this video. 

Plantar fascial night splints

Plantar fascial/achilles night splints are devices that we are able to dispense in our practice that aid in stretching out the achilles tendon and plantar fascia. We have a good number of patients that have resolution in heel pain with the use of just stretching exercises, night splints, and icing. Night splints are generally used while sleeping or resting at home. The night splints that we dispense are preset at 5 degrees and after a week we have our patients reset the splint to 10 degrees. Typically heel pain patients will use the night splints for 4-6 weeks.
A majority of insurances cover plantar fascial/achilles night splints. It is easy to use and is a nice conservative treatment option for heel pain.
