Hi Ritapearl, just wanted to add that the same thing happened to me about bleeding. Im on the 7% sodium solution and things seem to go along fine, then out of nowheres Ill bleed, usually for a day, then it tapers of and Ill go back to regular mucus, sometime slightly pinkish which probably means blood but what does cause this? My Dr says if it isn't cupfuls, it should be ok, that the vessel probably get agitated at times and will bleed. Thanks for bring up the question. Hal
