Hi. I'm 20 years old . Whenever I eat sweets , ice creams , drink any beverages or any citrus fruits or when the season changes , I suffer from severe cold with flowing nose. Because of dust also , the problem exists . I have this problem from childhood. At least once in a month I consult the doctor for this problem. I'll be alright until I use the medicines . After that problem persists. I can't go to college regularly because of this problem. Please help me. And give me a suggestion that to which doctor I should consult. Kindly looking forward for your reply.
