Plantar fasciitis is a common condition affecting the foot, caused by irritation and excessive strain of the plantar fascia, a thick band of connective tissue that runs along the bottom of the foot, connecting the heel bone to the base of the toes. This tissue helps support the arch of the foot and absorbs impact during walking, running and other weight-bearing activities. When subjected to repeated stress, it can become irritated, resulting in pain and tenderness, usually around the heel and along the sole of the foot. Symptoms are often worse when taking the first steps in the morning or after sitting or resting for prolonged periods. The pain may ease with movement but can return or worsen after extended periods of standing, walking or exercise. 

Contributing factors include prolonged standing, increased physical activity, unsuitable footwear, tight calf muscles, reduced ankle flexibility and changes in foot mechanics. Although plantar fasciitis can be painful and affect everyday mobility, it is generally a manageable condition. 

Treatment:

Focuses on reducing strain on the affected tissue, relieving pain and gradually restoring normal function through appropriate activity modification, insoles, strengthening exercises and supportive footwear. Recovery varies between individuals and may take several months, with consistent management helping to improve symptoms and reduce the likelihood of recurrence.
