I have been having stomach and extreme back pain that comes and goes spuratically with extreme bouts of diarrhea.  I have noticed that it is at its worst right before my menstral cycle.  I also notice that right at the end of my cycle I get left ear, neck pain.  Maybe they dont go together but I am concerned due to my family history of cancer
Hi there. Diarrhea with menstruation commonly occurs in females with dysmenorrhoea (painful menstruation). Pain causes increase in prostaglandin secretion in body resulting in back pain and diarrhea. Treatment consists of taking Naproxen or any other over the counter NSAID which will decrease prostaglandin secretion and thus alleviate your symptoms. I hope my advice has helped Good luck
