Well its definetly possible that you are having a partial obstruction. I would suggest that you get in with your GI soon to have tests ran to look for any narrowing. With my obstructions, whether partial or not, I have pain that comes in waves much like labor pain around the belly button area, cannot move air in either direction, nausea and then eventually vomiting.
I am thinking you at least might have some narrowing going on because of the "lots" of nausea and it being worse in the morning.
You should probably get your GI to do a small bowel follow thru and see if you have something going on in there.
Also, its very normal to have what you call referred pain. This is when the cause of the pain is in one area, but you feel it in another.
Keep us posted on what the doctor says.
