Cold-like symptoms with throat, ear itch

I'm experiencing cold-like symptoms (a runny nose - my hankerchief is always in use) for a prolonged period (over a year). Throat itching followed by ears mostly happens when I wake up in morning or evening, followed by constant sneezing and runny nose. No fever. The portion from the head to throat feels congested, although I'm able to focus on work. Doesn't lead to weakness, just uncomfortable. Other symptoms: stuffed nose, ear congestion. These symptoms have now started to show up suddenly, sometimes mild and sometimes severe like last night. The ordeal sometimes lasts for over an hour, and there have been many times when I'm okay within 15 minutes. Drinking hot water sometimes gives temporary relief. I'm not taking any medication for this problem. Such was not an issue back in Chennai and Bombay. Happens only in Delhi.
