I don't want to confuse or send you down the wrong path. But consider a food intolerance, allergy, or candida. I myself would not take Colloidal Silver . If the GB was blocked you'd be having some pain. Through elimination maybe you can figure out what is making you break out. I do enemas, seems more natural than taking something that appears to be a laxative. Sometimes a supplement just does not agree with the body as well. http://ibdcrohns.about.com/cs/otherdiseases/a/greenstool.htm
The thing with your penis, I really have no idea, are the area's tender to the touch?, do you easily bruise?
