You have LPR. See an upper GI specialist for at least an endoscopy with treatments of possible meds or surgery.
I have the EXACT same thing...the side of my face goes numb...tingling on that side of my head and pop rock feeling in my throat...I really wish I could figure out what it is instead of spending a ton of money and finding out it is anxiety!!
The best person to discuss these sensations with are your GP and you have to stress your concerns about them so that he can have you examined with an ear, nose and throat specialist to put your mind at ease.
