Pain on the left abdoman is pancreas or pleen if it is above the naval, colon if below.
I would certainly opt for the 4part Beck protocol. Colloidal Silver , zapping or bloodelectrifying, the Magnetic Pulser and freshly ozonated water.
I drink 8 - 24 oz of Colloidal Silver daily self-made, zapp a minimum of 2 hours daily, use the Magnetic Pulser 1 - 2 hours daily and drink a minimum of 1 - 2 quart freshly ozonated water.
Check out Sota Instruments for the Magnetic Pulser and the water ozonator. I use the Terminator for a zapper. I only received it today, but its causing some lively activity already. It is recommended to use the Terminator 24/7. Wherever I place it on the body there is much twitching. Hm, scarry! :-)
