I started doing the same thing especially for the saline spray. Bound to help shrink tissues when it goes up there cold and de-congest. I'm going for another MRI today. This one with contrast. The last one showed chronic sinusitis and some weird brain activity [big surprise huh ? ] that may suggest an old stroke or the slight possibility of ms. We shall see about that as well. An MRI of the head is a claustrophobic nightmare. Thankfully I don't have problems with that.
