I had problems after one of my flushes with a severe attack. I took another dose of grapefruit juice and oo right away and took more Epsom Salts . Since, I have still followed Dr. Clark's method except that I use 3/4 c. oo instead of just 1/2. I get better results and have had no pain. Maybe she has a stone stuck or something and little bit of extra lubrication may do the trick. Not an expert's input, just something that happened to work for me.
