Allergic to dust mites I presume. Sneezing, with itchy nose and ears for 1 to 3 hours . After that cold will start and continues for days together. Watery discharge through out the day and night and always nose block. Headache also I have because if this continuous cold. My child is perennial. There is not even a single day where I don't have cold. I anyways carry handkerchief along. Not ever 2min can survive without a handkerchief. Headache on my left eyebrow at only one point
