Take Epsom Salts for your pain. 1/4 to 1/2 teaspoon will help all that pain.
When I was in your shape, I jumped right in and did Dr. Clark's Liver Flush BEFORE I did a colon and parasite cleanse.
I was so inspired by my positive results, I began to flush every two weeks until I saw no more stones. Was that the way Dr. Clark teaches? No, but at the time, all I cared about was healing my gallbladder. I could have cared less about any parasites or a healthy colon.
In between the liver flushes, I began a series of parasite and colon cleanses. They worked, too.
Just remember, it is YOUR body and it will tell you what it needs. All you have to do is listen.
