Ear pain and throt itchy. Health issue.

I have a problem from last 5-6 years where below thing happen to me 1- while I talk, I feel some itching in my throt. 2-At the same time my  ear start paining , simultaneously while I talk and the pain persists even after I stopped talking . If I am not wrong it's my ear drum which vibrates/get impacted  due to itchy throt  and pain start in ear. The problem have started after I have a mouth joint pain back in 2014-2015 , which was cured after I applied hot water cloth around that  . When I apply some hot water gargling or take steam water I feel relaxed. Last time when I consulted to a doctor , Doctor pointed out that this happening due to cold and advised me to stay away from cold food and drinks , which I fail to stay away from many time. Need help to understand the problem and assistance on which doctor I should consult to cure this health issue.
