Probably a really minor thing but definitely annoying, has anyone ever had a runny nose lasting almost a month? Started out with a flu type illness, coughing, sneezing feeling generally weak but I feel completely fine now but the runny nose won't stop, it's like a tap constant and I'm wondering why it has not gone, I've used otc meds etc but it's just not shifting! Is it a weather thing? Never had a cold last this long
