I, as a successful flush veteran (about 3 years flushing history, appr.16 flushes), would advise you to stay away from your doctor. Your flush results tell me that you have bigger stones on their way to come out. You felt great that means that is the way to go.
You should be for a while (few days) on no fat diet. Drink lots of freshly squeezed apple juice (it dissolves the stones). If pain will be too bad, drink some magnesium suphate with water, it helps to release the pain.
When you will feel ready do another flush. It should help with your condition now. After that plan on flushing every two weeks untill no stones.
