Do you have sudden pain in your foot/feet when you step out of bed in the morning? You may have plantar fasciitis! Plantar fasciitis is an extremely common foot injury. Plantar fasciitis mainly occurs in athletes and runners or people wearing poorly constructed shoes. With proper care and treatment, plantar fasciitis can be cleared up in a few short weeks or months. See your doctor if you are experiencing any signs of plantar fasciitis.
