Maybe you are dehydrated? I'll let other fasters speculate as to the cause-- but meantime you can get a plain saline nose spray and use it several times a day. This will dampen the tissues so that the mucus isn't so dry and will come out more easily. Also, if your nose is bleeding, chances are it's because the Q tips and hard mucus are ripping the delicate membranes in your nose. Saline will help prevent that too.
