Mine started like that about 5 years ago. Now I have stabbing pains too and the intensity is much worse. 2-3 days on left side, 2-3 days right. I have always suspected parasites and have done a lot of zapping in the past with little success but after passing some ascaris in urine and bm am pretty sure I need to do something. I just started zapping and taking Black Walnut and Cloves, will also periodically do a homeopathic treatment and see if that combo helps. Won't know until my next cycle since mine are usually post-menses. My last ones were so bad I'd have gone to the ER if I wasn't in so much pain.
Treating with Field Control Therapy. Also my New Year's resolution is to do more detoxing, eat healthier and exercise.
