Foot pain may be a precursor to the following diseases: First, plantar fasciitis: If you often walk with weight or strenuous sports, such as walking up and down stairs, walking long distances, hiking, often sprinting, etc., there will be an increased load on the plantar fascia, causing increased tension in the plantar fascia, which over time will lead to plantar fascia strain, resulting in inflammation of the plantar fascia, manifested as pain in the palm of the foot or pain in the heel area . Second, lumbar disc herniation: when the herniated disc tissue compresses the spinal nerve root, there will be radiating pain in the lower limbs. Third, pear-shaped muscle syndrome: when the pear-shaped muscle compresses the sciatic nerve, there can also be radiated pain in the lower limbs, and the pain can radiate to the foot.
