Well, the Liver Flush will clear up your allergies, which are related to sinus problems.
But, when toxins are released into your system from a flush, the toxins can cause problems. They may aggrevate your sinuses and could be causing the bumps you are describing.
Did you take ornithine when you flushed? The ornithine pills help absorb the toxins.
So, I would tell you to just keep flushing until you see no more stones. Good luck and good health!
