Left heel pain may be indicative of fasciitis in the heel area, heel bone spurs or trauma to the heel such as a fracture. 1. Fasciitis: the older you get, the softness and elasticity of the fascia of the foot will gradually decrease, making it easy to develop fasciitis. Long-distance runners or long-term walking will cause pressure and friction stimulation of the heel, resulting in long-term damage to the fascia, thus resulting in heel pain. 2. Heel bone spurs: due to long-term walking or sports, resulting in the Achilles tendon and bone attachment point of the position of strain, cold aseptic inflammation, with the deposition of calcium salts and thus the formation of bone spurs, calcification, as well as bone stimulation of the surrounding tissues manifested as heel pain. 3. Heel trauma: such as heel bone fracture or ligament strain, soft tissue contusion, muscle strain, etc. will lead to heel pain. It is recommended that patients go to the hospital when they experience discomfort.
