Hi Lori...have you tried just taking a couple of teaspoons of ES in water (without doing the whole flush procedure) to see if that relieves your side ache? I know that Dusan recommends that for people in pain. It's totally safe.
Maybe you need to do a Bowel Cleanse as well (to help with digestion and elimination)...If you read Journey to the Center of the Colon at wwww.thedoctorwithin.com site you will see how the waste that hangs around for years within your intestines expands and pushes against all your other organs causing autointoxification! Basically..the toxins seep into other organs and your bloood stream causing more problems! Maybe your gallbladder can't heal because you need a bowel cleanse? You never know!
Take a look at the article and see if it inspires you.
Here's a post on Bentonite & psyllium bowel cleansing, too: //www.curezone.org/forums/m.asp?f=153&i=1061
