Hello, I have had severe symptoms since september. I have uncontrollable flatulence, i feel nausious, bloated and i have abdomin pain. I have severe constipation but the most disturbing thing is the flatulence. I have also noticed that my legs turn blue when i shower. I also have pain in my knees, wrists, ankles and elbows. I have been tested and do not have celiac disease, lactose intolerance, artheritis nor parasites. I had the same diet in september as i had had years before. I did not have and I do not have stress or anxiety. I have tried all kinds of diets - dairy free, gluten free, sugar free, starch free etc. I am sure it is not stress or dietary related. What could be causing my various problems? Could it be my thyroid? Thank you.
