i have had blood coming out of my bottom for about 6 months when i go for a poo it gushes, i saw the doctor when i first noticed and he did a stool test , which came back clear , so he dismissed me. now i have more problems and i do not know if they could be related , i have a sore left breast , pain in my rib cage ,more left than right , it hurts to touch , i am also suffering constant severe pain to the back of my head it goes down my back , and the bottom of my back is also painful along with my calfs, i have no fever.
