Heel pain is a common foot issue. It can result from inflammation, bone changes, nerve compression, and other factors. It occurs under the heel or just behind it, where the Achilles tendon connects to the heel bone. Sometimes, it can affect the side of the heel. In most cases, heel pain resolves without treatment, but sometimes, it can persist and become chronic. Heel pain may occur due to a single injury, such as a twist or fall, or from repetitive stress and pounding of the heel. Flat footwear
