Seems like nasal rinses have been good for me but are you finding your nose to be very dry afterwards? Is there any issues with rinsing twice a day forever? I use a saline spray which helps moisturize afterwards but I’m going to try and get the Mayo spray you mention if I can get my ent to help out.
@zaa I haven't noticed my nose being very dry. Also have not heard of any issues with using a nasal rinse twice a day. The nasal spray has helped a lot for me but the little spray bottle leaves a lot to be desired (IMHO). It has a 2 inch plastic tube that is really not flexible attached to the top of the pump bottle and you have to hold the bottle at an angle to pump which is OK when the bottle is full. Now that I have less than half left in the bottle I have to mess with it because I can't bend the tube to keep the bottle upright when pumping the spray. It's definitely worth a try to avoid any kind of nasal surgery.
