What Could Lead to Numbness in the Upper Left Side of the Abdomen?

Numbness in a specific area like the upper left abdomen may happen when nerves do not work correctly. One possibility is irritation or damage to the nerves near the spine due to a herniated disc. For example, when a disc in the thoracic (middle back) area pushes out, it might press on nerves that send signals to the abdominal wall. This can create a feeling of numbness or tingling in that area. Another cause is a condition called ilioinguinal neuropathy. This occurs when the ilioinguinal nerve, which helps provide feeling in parts of the lower abdomen and groin, becomes irritated or damaged. Although the ilioinguinal nerve is usually linked to the lower area, nerve issues can sometimes be unpredictable and spread to nearby regions. It is important to talk to a doctor if you are experiencing numbness so they can check your nerves and spine and help decide the best steps to take.
