Patients with lumbar disc protrusion are advised not to wear high heels for the following reasons: 1. It will lead to aggravation of disc protrusion: Because when wearing high heels, the posture of the spine will change, the lumbar spine will be excessively convex, which will cause the pressure and load on the disc to increase, causing aggravation of disc protrusion, which may cause aggravation of lumbar pain. It may also cause aggravation of nerve root pressure, manifesting as radioactive pain in the lower extremities, which is significantly higher than the original, and numbness in the feet, which is also significantly higher than the original. 2, will lead to plantar fasciitis: wearing high heels will also change the weight-bearing point of the sole, which is very likely to cause plantar fasciitis, manifesting as chronic pain in the sole.
