I know exatlcy how you feel, my dad is exatlcy the same except he sounds like hes choking half the time. Apparently it is something to do with your throat and not actually your nose. He did try a throat spray but that didnt work and then i was reading in my good health magazine that over the counter remedies do not help.The best thing to do is see an ear, nose throat specialist as they can determine if there is a problem advise the best solution. In some cases surgery is required to fix the problem, but in others there are simple things that can be prescribed.Good luck!!
