Plantar fasciitis is one of the leading causes of foot pain. It happens when the plantar fascia, which is a thick band of tissue running from your heel to your toes, becomes irritated or inflamed. Most people notice a sharp pain under the heel when taking their first few steps in the morning. The discomfort often eases as you move around but may return after long periods of standing or walking.
Several factors can increase the risk of plantar fasciitis, from tight calf muscles to poor footwear. Fortunately, this condition usually responds well to conservative treatment. Rest, supportive shoes, gentle stretching and strengthening exercises can gradually reduce pain while improving the function of the foot.
The Mayo Clinic notes that “factors that can increase your risk of developing plantar fasciitis include aging, obesity, certain types of exercise and occupations that keep you on your feet for long hours.”
Tendonitis develops when a tendon becomes irritated through overuse or repeated strain. One of the most common types is Achilles tendonitis, which affects the large tendon connecting your calf muscles to your heel. Pain is usually felt at the back of the ankle or just above the heel, especially during walking or running.
Another common condition is posterior tibial tendonitis, which affects the tendon running along the inside of the ankle. This tendon supports the arch of the foot, so irritation may cause pain along the inside of the ankle or contribute to a flattening of the arch over time.
When your feet or ankles hurt, your first instinct may be to avoid movement altogether. While rest is important during the early stages of an injury, complete inactivity often leads to increased stiffness and weaker muscles. Instead, focus on gentle, pain-free movement that restores mobility without placing too much stress on the injured tissues. If any exercise causes sharp pain, stop immediately. Mild stretching or muscle fatigue is normal, but pain should never become worse during your workout.
