Plantar fasciitis manifests as pain and inflammation along the bottom of the foot, particularly at the heel where the plantar fascia—a thick band of connective tissue—attaches to the heel bone. Patients typically experience a sharp, stabbing pain with their first steps in the morning or after prolonged periods of rest. This discomfort can decrease slightly as they start moving but may return with prolonged activity or standing.

The condition often affects daily life by causing significant discomfort during walking or standing, making it difficult to engage in routine activities. The persistent pain can lead to compensatory changes in gait, which may result in additional strain on other parts of the foot, as well as the knees, hips, and lower back. Managing plantar fasciitis usually involves rest, ice application, stretching exercises, and wearing supportive footwear or orthotic inserts. In persistent cases, physical therapy or medical interventions such as corticosteroid injections might be necessary to alleviate pain and promote healing.
