Hello Doctor, I am 26 years old. Since December 2024, I am facing a repeated problem of sneezing and cold. Earlier I never had such issues. My main symptoms are: As soon as I wake up in the morning, sneezing and cold start immediately. Frequent sneezing before the cold fully develops. Running nose, and sometimes mild nasal blockage or congestion (but not completely blocked). The symptoms last for 2–3 days, then I get relief for a short while, and after that, it suddenly starts again. Medication tried: I take Cetirizine tablets whenever the symptoms start. It gives me relief for 1–2 days, but then the cold comes back again. This has been happening continuously since December, and I am very tired of it now. Could this be due to allergy or some sinus-related issue? Kindly suggest what tests or treatment I should go for. Thank you.
