Nerve issues refer to problems that affect the nervous system, which includes the brain, spinal cord, and nerves throughout the body. These issues can cause a variety of symptoms, such as pain, numbness, or weakness in different areas. Common conditions include neuropathy, which often results from diabetes, and sciatica, where pressure on the sciatic nerve leads to discomfort in the lower back and legs. Many factors can contribute to nerve issues, including injuries, infections, and chronic diseases. Lifestyle choices, such as poor diet and lack of exercise, can also play a role. Early diagnosis and treatment are essential to manage symptoms and prevent further damage to the nerves.
