The symptoms of numbness in the feet can occur after having pear-shaped muscle syndrome, and the main thing that occurs after having pear-shaped muscle syndrome is the symptoms of damage to the sciatic nerve. The sciatic nerve is the largest nerve responsible for all skin sensations as well as limb and muscle movements in the lower extremities, so when the sciatic nerve produces damage it can completely cause numbness in the feet. The most important symptom of pear-shaped muscle syndrome is sciatic nerve injury. Since the pear-shaped muscle is the outlet of the sciatic nerve, when the pear-shaped muscle becomes diseased, it will compress the sciatic nerve, thus leading to sciatic nerve injury, which will eventually cause symptoms of pain and numbness in the limbs, including the symptoms of numbness in the feet.
