Plantar fasciitis is a dull to severe pain in your heel caused by a strain and inflammation of your plantar fascia. The plantar fascia is a scientific name for “foot tissue.” This particular tissue is a ligament attached at one side to the heel bone. At the other side, the tissue fans out to attach at the base of each of your five toes. Plantar fasciitis is the name for the condition that develops when that tissue becomes inflamed. When the plantar fascia is excessively stretched, micro-tears can occur, causing this swelling and subsequent pain.
WHAT CAUSES PLANTAR FASCIITIS?
Plantar fasciitis can develop when your feet roll in too far as you take each step. This rolling in, known as over-pronation, can happen for many reasons. It can be due to excessive weight gain, pregnancy, quickly increasing physical activity, tight calf muscles, poor biomechanics or merely wearing unsupportive, flat footwear. When your feet over-pronate, your arches can collapse, putting strain on the tissues in the bottom of your foot. Plantar fasciitis can also be caused by excessive pronation; sudden increases in training mileage; beginning speedwork; wearing worn running shoes; running on hard surfaces, like asphalt or concrete; or wearing high heels all day before switching into flat running shoes.
SYMPTOMS OF PLANTAR FASCIITIS
A sharp pain in the center of your heel will most likely be one of the biggest symptoms of plantar fasciitis. A classic sign of plantar fasciitis is when the pain is worst during the first steps you take in the morning.
