Ear-Nose-Throat Problems

Daily night or sometimes day time Im feeling hot sensation or some burning feel behind ear and neck(no sweating). While lying down on bed it's not going away even after under the AC. I don't have any medical conditions diagnosed but this one is really weird.

In India every now and then I am getting throat infection! Without eating or getting exposed anywhere! I was in the Uk for past 1 year i roam around with degrees being 2 or 3 and had never faced any issues or infections. Now I have moved back to India and in the second month itself without any travel history and cold food consumption i am struggling with fever and tonsils. This happens almost 3-4 times a year when I am in India. Will flu shot help me? Or somethign! I stay in precautionary measures and still i get so sick always! Help me what to do!
