I feel for you! That must be a little frustrating!
I was MCing and stopped today, and one of the reasons I stopped was my liver/gallbladder. Like you, I've done the l/g flushes before and it seems they hurt more now than before I ever started cleansing. Actually, that's a fact. That area does indeed hurt more now than before I started cleansing them.
One thing I was talking about today to some local health-minded people, was that the liver is still filtering during the MC, and if we're successful in releasing stored things back to be eliminated, maybe the liver is doing it's best to keep up and gets gooked up again.
