Left heel pain is not necessarily due to gout, but may also be caused by other diseases, and the cause needs to be clarified and treated accordingly. Gout patients with left heel pain mostly occur suddenly at midnight or early in the morning, and the pain is intense, accompanied by redness, swelling and heat, and blood tests may have hyperuricemia. The patient’s left heel pain is most commonly associated with Achilles tendonitis, which is mainly related to excessive exercise, insufficient warm-up before strenuous exercise, and flat feet. These patients usually experience pain and swelling in the Achilles tendon area when walking, running, and other exercises, and may have joint stiffness in the chronic phase. Generally, after going to the hospital for examination, the doctor can make a diagnosis through physical examination, X-ray examination, MRI, etc., and give the corresponding treatment. It is recommended to visit the orthopedic department of the hospital after the appearance of left heel pain. If it is gout, it should be treated actively to lower uric acid, and patients should avoid foods with high purine content, such as heart, liver and kidney of animals, and avoid drinking alcohol. If it is other heel diseases such as Achilles tendonitis, the patient should take sufficient rest and can apply hot compresses to the heel area to promote blood circulation and relieve pain.
