I asked my daughter's doctor this before, but was told it was likely due to allergy. Yes she does have known allergies, and her reaction is very typical in this sense, sneezing, coughing etc. But what I don't understand, is why her sneezing has always been so extreme. Since she was born, she would literally sneeze violently, nonstop, repeatedly for hours on end. It affects her sleep and her well being, and it's difficult to convey how extreme these bouts are. If perfume is sprayed nearby, she will violently react straight away. With just about anything in fact.
She's just developed another cold, and as per usual, started sneezing around 3am Sunday morning, did not stop, bar short 2 minute gaps here and there, until around midnight last night. Then it suddenly stops, and she feels it in her throat, then starts feeling it move down her chest a day or two later. Sometimes it stops at viral bronchitis, other times moves to her lungs and she needs IV. I know this can be a familiar pattern for many with colds, but I just wondered is this type of sneezing also familiar to anyone? A quick google seems to indicate it certainly is with dogs, but I can't see anything in relation to humans?!
