Itchy in upper mouth
I have a constant feeling of itch on my palate ( upper mouth). Its been that way for a month now. I went to an ENT, he said i have redness on my uvula and that is the reason i am feeling itchy on my palate. He says it is because of some allergy and has prescribed me anti histamines and citravet. What i want to know is how can an allergy remain constant for a month. Also, i am getting scared if this is something major . Please help ??
