Hi Colleen,I experiance the same thing very often.This time of year it is easy to get dry sinus.I went to walmart and bought one of those nasal flushs.They really clean out your sinuss good and help me prevent bronchitis.Its called NeilMed Sinus Rinse.I thought the same thing as you the first few times I blew dry blood out.Also a humidfier would probably help also.Good luck.
