Globus hystericus. belly bloating, burning sensation, gurgling noises. pinching feeling at sides and on the sides of the bellybutton. lower back ache?

Could it be stress?: When taken together, globus sensation ("feeling of a lump"), air swallowing with resulting belching, & dry mouth/ throat are most consistent with stress/anxiety. So can be your "gurgling noises & pinching (poorly localized as described)." Managing your stress (& reasons for same) may be your key to relief. To be sure however get evaluated to rule out organic or motility disorders here.
