Other common injuries in runners include medial tibial stress syndrome, also known as “shin splints.” This causes pain over the shins and is more common in beginning runners. Long-distance runners can get stress fractures, small fractures of the bone that result from repeated “stress” on the bone, most often in the lower leg, hip, or foot. Other foot problems include Achilles tendinitis and plantar fasciitis. Achilles tendinitis causes pain along the heel cord (Achilles tendon) at the back of the ankle, whereas plantar fasciitis causes pain at the bottom of the foot or the heel itself. Plantar fasciitis usually feels worse after a period of rest, such as in the morning just after getting out of bed.
