No stones, thickened walls, and sludge. What do I do? I am having a function test on Dec. 11. Can I make a difference between now and then? I have done 3 flushes. Stones on 1 and 2. Third was unproductive. I feel like I am carrying around a tennis ball in my ribs, while having a heart attack. Lord knows if a real heart attack came I would never know!
