Numbness in the right upper quadrant is most often linked to nerve-related issues. Common causes include intercostal neuralgia, nerve injury following abdominal or thoracic surgery, and, in rare cases, systemic conditions like polyarteritis nodosa that damage peripheral nerves. Skin conditions such as shingles and spinal nerve compression can also trigger localized numbness in this area.
Because numbness may signal anything from a minor nerve irritation to a more serious underlying condition, identifying the cause early matters. A free, instant, online symptom check can help you clarify possible causes based on your specific symptoms and guide your next steps—whether that means monitoring at home or seeing a specialist promptly.

Not seeing your question? No worries.
Submit your own QuestionThere are several reasons you might feel numbness in the right upper part of your belly. One possible cause is intercostal neuralgia. This means the nerves running between your ribs become irritated or inflamed, which can lead to numbness or a tingling feeling in nearby skin.
Another possibility is that if you have had recent laparoscopic (keyhole) surgery, sometimes the nerves in the abdominal wall might get injured during the procedure. This injury can cause numbness or even weakness in the area. In some rare cases, a condition called polyarteritis nodosa, which is an inflammation of medium-sized blood vessels, may affect the nerves in the abdomen and produce symptoms like numbness. Each of these causes affects the nerves that send signals of touch, causing them not to work normally.
If you or someone else is experiencing these symptoms, it is important to see a healthcare provider for a proper evaluation. To help identify what might be causing your symptoms, you can start by taking a free symptom checker test that provides personalized health insights based on your specific concerns.
