Right side tongue, throat, ear constantly hurt and feel odd. Had sinusitis surgery 3 months ago. ENT looked at my throat with endescope but saw nothing.

Unclear. Need a second opinion and not necessarily. if the ENT doctor is very competent, ask him who would be good for a second opinion. The doc will be forthright and should tell you either an ENT or maybe a neurologist. The cause of pain should be followed up.
