What are the potential causes of numbness on the right side of the abdomen?

Nerves send signals for feeling all over your body. When a nerve becomes injured or squeezed, it might not send its signals well, causing numbness. One reason can be intercostal neuralgia. This is when the nerves that run in between the ribs (and extend toward the abdomen) become inflamed or irritated. Sometimes a virus like shingles, injuries, or surgery can trigger this. Another possibility is meralgia paresthetica, which happens when the lateral femoral cutaneous nerve gets pressed. Although it usually causes numbness or a tingling feeling on the outer thigh, the compressed nerve sometimes can affect sensation close to the abdomen. Finally, ilioinguinal neuralgia occurs when the ilioinguinal nerve that passes through the lower abdomen and groin area is irritated. This irritation might happen if there is an injury, pressure, or surgery in the area. Each of these conditions affects nerves in their own way, leading to numbness and sometimes pain.
