I suffered horrendous period pains (cramps in days 1&2)from the ages of 11 to 32, such that I was on the verge of passing out as the pain was so intense. I tried Feminax and Phenacitin. I used to need days off sick from teaching. At a Family Planning Clinic I was told by a male Dr. to use Aspirin, which is totally useless, and I was so angry I could have hit him. I had Harley Street progesterone therapy for period pain at Katharina Doulton's clinic and a few months afterwards developed a breast lump which needed removing. That too was no good for the pain. Then at the age of 32, after over 20 years of suffering, a wonderful, now retired, GP in Beccles, Suffolk prescribed the anti-arthritic drug, SYNFLEX. Bingo!! At long last my suffering was over. Twenty minutes after taking one of these tablets the pain would melt away.
