About 3 days ago I noticed a numb patch on my upper right abdomen. There is no pain, and I feel fine otherwise (no weakness, nausea, vomiting or lack of appetite). It is located just below my rib cage for about 2-3 inches and then wraps around the side and a few inches into my mid/lower back. just a strip about 2 inches wide from the bottom of my rib cage about 8 inches long wrapping around my back.

I know this is right in the area of the liver - but I don't have any other "liver symptoms" that I can tell. 

The area on my abdomen gets a little itchy occasionally and sometimes I feel pressure - but I think that is just the oddness of feeling the numb area.

I do have lower back issues and am diabetic (but in good shape).

Only other bit of info - is sometimes I feel like the numbness goes to the back of my head or the right side of my face - BUT, then i can't really tell ... i think its in my head now.

Any ideas?
