Sensitivity near navel gluten related?

hello all,

29 male. I've recently been having nausea, gas and bloating. It has gotten a lot better after seeing the doctor. They think its gluten related so i am going gluten free for a while. I am feeling a tenderness near my navel area which i believe is caused by gas. My navel is not tender at most times; only when i feel or hear the gurgling of gas in my belly. At such times putting pressure near the navel also makes me want to pee. Wanted to see if anyone else had this happen to them.
