I'm scared, should I do a flush-Please opinions needed

Hello, I've been having lower left pain like a knife inside my body trying to push out "something". I thought it was a bladder infection due to pressure, so for 3 months now, I have been using Cod liver oil, oil of oregeno, garlic, Olive leaf Exract, and Grapefruit seed extract. Then I bought a bottle of Colludial(sp)Silver (CS) after the GYN assured me it was "not his department", and that my urine showed some blood in it. Pain is off/on. After finishing the CS, and still taking all the above, constipation was followed by a bowel movement that looked like shiny grapes, but I don't think they floated. Question 1-Could this of been bacteria released by all this I took and the CS? An ultrasound(already scheduled) after the weird bowel movement showed gallstones if that's what "Cholelithiasis" is? And, "Small Gallbladder polyp" along with "Mild atrophy of the renal cortex bilaterally". I saw a Urologist that was already scheduled, and he thinks I might have a Hernia which makes sense since I've been carring around a bunch of books lately. I'm 45, female. Am I a good candidate for a liver(gallbladder)flush? I have 3 children, one mercury poisioned (ie., Autism), so I would like to err on the side of caution. When should I run to the ER? Interestly enough, I have not had the pain on lower left for a few days, but I have not carried my books since last Monday night. About a year ago, I threw up bile two months in a row. Also about a year ago, My husband saw my body start to shake beginning with my right leg on up, and then on my left side. I was asleep and did not notice it, but I believe him because he was terrified thinging that I was dieing. I've also had presistant indigestion for almost 1 year, which I thought was from eating pineapples for 2 weeks straight during the summer. And, my cholesterol and blood pressure have been going up over the last year. Everything I've read makes sence due to the gallbladder stones and I want them out ASAP. Thanks in advance. Roxy2006
