Hi to you all. I have also experienced the same you have listed. I was cramping also and went to the gyno...19 blood tests, and a urine test. All fine. My only guess is a diseased gall bladder, really can't be detected, just have to have it removed if symptoms are too severe to live with. Milk can cause this to flare up and certian veggies. I rarely have the flare up with my gall bladder, which is associated with right rib cage pain, pain between the shoulder blades, gas, bloating, bm's can be different from day to say. Fever and chills even, headaches almost daily. I even have irregular period for the last two months and I am super, super regular. I personally believe gall bladder or ovarian cycts. UTI and Kidney infection can cause most of this too, but I have had those ruled out. You can buy otc UTI tests at Wal-Mart $30, even colon cancer screening kits. Kidney infection can be deadly if gotten into the blood steam - so if fever and chills are present go to dr ASAP. If I find out anything I will update, thanks and I hope this helps.
