I'd say - flush it out! I passed some 'big' stones and didn't feel a thing. Visit my flush page.
As far as 'uncomfortable' goes... Get used to it. Small pea size stone will get you there. Just learn to get over it. Use hot water bottle to relax your liver/gb area.
I did my lust flush around lust full moon - just a few peanuts out, biggest about 1 cm across. And I felt some pains in a previous month. I feel better now and wander if I make my lust flush for this year next full moon.
