Overview

Plantar Fasciitis

Plantar fasciitis is a common cause of pain around the heel and bottom of the foot. It involves irritation or degeneration of the plantar fascia, a strong band of tissue that connects the heel bone with the toes and supports the arch of the foot. Pain is often most noticeable with the first steps after waking or resting.

Bursitis

Bursitis is inflammation or irritation of a bursa, a small fluid-filled sac that cushions tissues around joints and reduces friction during movement. It commonly affects the shoulder, elbow, hip, knee, or heel. Repetitive movement, prolonged pressure, injury, infection, or inflammatory conditions may contribute. Symptoms usually include localized pain, tenderness, swelling, and discomfort with movement or pressure. Treatment depends on the cause and may include activity modification, physical therapy, medicines, drainage, or treatment of an underlying condition.

Diagnosis

Plantar Fasciitis

Plantar fasciitis is usually diagnosed from the pattern of foot pain and a physical examination. The healthcare professional may examine the heel and plantar fascia and assess foot movement, walking pattern, and calf flexibility. Imaging is not usually required for typical cases but may be used when symptoms are persistent, severe, or suggest another cause of heel pain.

Bursitis

Bursitis is usually diagnosed through history and physical examination. The location of pain, tenderness, swelling, movement-related symptoms, and recent activities help identify the affected bursa. Imaging such as ultrasound or MRI may be used when the diagnosis is uncertain or another injury is suspected. If the bursa is significantly swollen or infection is suspected, fluid may be removed with a needle for laboratory analysis. Fever, redness, warmth, or rapidly increasing swelling can suggest septic bursitis.

Prevention

Plantar Fasciitis

Plantar fasciitis risk may be reduced by maintaining a healthy body weight, wearing supportive footwear, avoiding sudden increases in exercise, and gradually building activity levels. Regular stretching of the calf and plantar fascia may be useful for people at risk. Replacing worn-out athletic shoes and modifying activities that repeatedly cause heel pain can also reduce strain.

Bursitis

Bursitis risk can sometimes be reduced by avoiding prolonged pressure on joints, using protective padding when kneeling or leaning, taking breaks during repetitive activities, and gradually increasing exercise intensity. Proper technique and conditioning can reduce excessive stress on joints and surrounding tissues. Treating underlying inflammatory diseases may also reduce recurrence. Cuts or skin infections near a bursa should be managed appropriately because bacteria can enter the bursa. Persistent swelling, warmth, redness, or fever should be evaluated promptly.

Risk Factors

Plantar Fasciitis

Risk factors include activities involving prolonged standing, walking, running, or other repetitive weight-bearing exercise. Flat feet, high arches, tight calf muscles, increased body weight, inappropriate footwear, and sudden increases in physical activity may increase stress on the plantar fascia. Occupations requiring long periods of standing may also contribute.

Bursitis

Risk factors for bursitis include repetitive joint movements, prolonged pressure on a joint, occupations or sports involving repetitive activity, direct trauma, increasing age, and inflammatory diseases such as rheumatoid arthritis or gout. Infection can cause septic bursitis, particularly when bacteria enter through damaged skin. Previous bursitis may increase the likelihood of recurrence if the activity or underlying condition continues. Proper technique, gradual conditioning, and protection from repeated pressure may reduce some risks.
