Is it normal to feel your pulse in abdomen, when you press it real hard. my tummy also feels hot?

Yes.: If you are thin you can press deeply in the abdomen just off to the left side of your bellybutton and feel the pulse wave in your aorta.

Maybe: While in normal or thin abd people on deep pressing one can feel the pulsating aorta, it is actually rare! pulsating in the abdomen with 'warm' abdomen can be a lot of things depending on thelocation and i strongly recommend professional help.
