Talk to Ent Specialist on Throat Problem

My throat is very sensitive, becomes sore everytime I drink something cold, and with it flu also happens, I also have rhinitis problem. I went to 2 ENT specialists both of said that I have tonsils problem that is why my sore is very sensitive but they both also said that it dont need to be operated. But every time my thorat feels irritated. Even when it is not sore. Everytime I drink cold water. I feel like the water is not flowing easily through my throat. Can anyone give some advice so I can feel normal...
