Ankle and foot pain refers to discomfort or soreness in the lower extremities, specifically the ankle joint and surrounding structures. The most common causes of ankle and foot pain include sprains and strains, which result from overstretching or tearing ligaments and muscles in the area. Other common causes include tendinitis, which is inflammation of the tendons, and stress fractures, which are tiny cracks in the bones due to repetitive impact or overuse. Additionally, conditions such as plantar fasciitis, arthritis, and nerve entrapment can also contribute to ankle and foot pain.
