👉 Cheilotomy is a medical condition that occurs when the nerves of the lower part of the spine (the lumbar region) send pain signals to the brain. This can cause severe pain, discomfort, and even numbness in some people. Cheilotomy is often caused by injuries or surgeries that damage the spinal cord. It's important to seek medical attention if you experience this condition frequently or have it as part of your healthcare history.
