Peripheral neuropathy is a condition where the nerves become weak or damaged, often leading to numbness in the hands and feet, tingling, muscle weakness, and reduced grip strength. Common causes include long-term diabetes (especially after 5 years), vitamin and mineral deficiencies, nerve-related infections, and immune system disorders. Early detection and treatment can help manage symptoms and improve quality of life. பெரிஃபரல் நியூரோபதி வந்தால், கை மற்றும் கால்கள் மரத்துப்போதல், ஊசிக்குத்துவது
