21 years old, 5ft6, 8st, had my adenoids removed when i was 6 due to sleep apnea and a constant runny nose and cold. There were complications with the procedure and I had to go back into surgery after i had a nose bleed and a blood clot in my throat. However I still have the constant runny nose but the mucus is clear and very runny unlike that of when I do actually have a cold, when it is white or green. Does this have anything to do with the fact that I no longer have adenoids, the complications with the surgery etc? What other reasons are there for a constant runny nose?
