Advice needed on a Big Calcified Stone?

History: Male 44, 310lbs, 6ft 2in. Mild Stroke in Oct 2000 , 2nd mild stroke in Dec 2002, Put on Plavix (anti-coagulant)
___
Oct 2002 Bleeding from bowell, black tar substance, abnormal liver enzymes, stomach problems, etc.

Eventually diagnosed as stuck calcified stone in bile duct. Barely avoided Pancreatitus.
__
Jan 2003 - Ultrasound reveals huge 2.8 cm calcified stone, Dr's recommend surgery. I refuse.
___
Afraid to cleanse, as huge calcified stone may rip ducts to shreds. So I started Chinese Herb solution in Jan.

Using Coptis, Curcuman, Gold coin grass from Julia Chang.

Last month added Hydrangea root, chanca piedra, apple juice, phosphoric acid, and Rowachol (Euorpean gallstone disolving drug based on essential oils like pepermint).

Recently experience more discomfort in liver area. Pressure, tingling, sometimes burnig sensation.

Liver enzymes normal and no bleeding.

Dr refused request for another ultrasound, ordered Hida Scan instead. Will have that result in two weeks.

New med plan starts July 1, new dr's of my own choosing, I am sure I can get all the Ultrasounds I want then.

Questions:
Is it safe for me to flush at all?
Should I wait till I get 2nd ultrasound to see if the big stone is now a bunch of little pieces?
Do I have any hope of saving my gb?

With previous strokes, and family history of father getting blood clots after surgery (leading to stroke, disability, and death), you can imagine that any surgery scares me to death.

I feel my first surgery will be my last.

Can I save my GB and life?
