What are the possible causes of numbness in the upper right abdomen?

There are a few possible reasons for feeling numbness in the upper right belly area. One possibility is that nerves in the skin or the muscles are being pressed or stretched, which might cause a tingling or numb feeling. Sometimes, problems like a hernia or inflammation in nearby tissues can affect these nerves.

Conditions that cause inflammation inside the body, such as issues with the liver or gallbladder, might also lead to unusual sensations, though numbness is less common with these. In one case report, a condition called polyarteritis nodosa, which affects the body's blood vessels and can cause nerve problems, presented with right upper abdominal issues. Additionally, factors like diabetes or other nerve disorders could lead to numbness if the nerves are not getting enough blood or are being damaged.
