Plantar fasciitis is a common condition that causes pain in the heel and bottom of the foot. It occurs when the plantar fascia, a thick band of tissue that runs along the bottom of the foot and connects the heel bone to the toes, becomes inflamed or irritated.

Plantar fasciitis is often caused by repetitive strain or overuse of the plantar fascia. Common causes and risk factors include:

Excessive Foot Pronation: People with flat feet or high arches may have an increased risk due to abnormal foot mechanics and increased stress on the plantar fascia.
Overuse or High-Impact Activities: Activities that involve prolonged standing, running, jumping, or walking on hard surfaces can strain the plantar fascia.
Tight Calf Muscles: Tightness in the calf muscles can contribute to increased stress on the plantar fascia.
Excess weight can put additional pressure on the feet, leading to strain on the plantar fascia.
Improper Footwear: Wearing shoes with inadequate arch support or cushioning can contribute to the development of plantar fasciitis.

The primary symptom of plantar fasciitis is heel pain, which is typically worse in the morning or after periods of rest. Other common symptoms include:
Sharp or stabbing pain in the bottom of the foot near the heel.
Pain that worsens with the first steps in the morning or after sitting for a while.
Pain that improves with activity but may return after prolonged periods of standing or walking.
Tenderness or inflammation in the heel area.
