When the plantar fascia becomes irritated from repeated stress—think: increasing your mileage too quickly without enough rest and recovery—it can cause a sudden sharp stabbing pain or a deep ache in your heel or along your arch. “You can get plantar fasciitis anywhere along the entire plantar fascia … but the most common spot to get [it] is directly on the bottom middle part of the heel,” says Canzanese.A classic symptom is first-step pain: discomfort that’s most noticeable when you get out of bed in the morning or after sitting for a while. “But you may also feel it during your run, especially when you push off your foot,” explains Yu.Underlying causes of plantar fasciitis:Muscle imbalanceTight calf musclesWearing the wrong shoesTraining errors“What the more recent research shows is that it’s a chronic repetitive stress.
