by the way Aimee, you can get Rhinaris (saline gel) to put in your nose that will help with the dryness. You should do this everytime you rinse. Do it with a Qtip.
The Saline rinse you are doing causes my nose to dry out too. Maybe you are doing it too often....how often are you doing it? Are you making your own solution or did you buy it? I know that if I do it too much my nose dries out and have even gotten a sore inside. I bet it can also cause dryness in your throat because you are getting rid of all the mucus and maybe that is too much. You need some mucus to drain down your throat. I would cut back on the saline rinse.
