It hurts when i poop and i got some blood, WHATS WRONG?
I am 15 but i never had this problem in my whole life. Its started when i started eating alot more meat b/c i needed protein for weight lifting. Now i start to get pain in my left part of my stomach. Its like the left abdomen. I ONLY GET THIS PAIN when i start to run for a while. ( i play sports). Also, when i go to the bathroom, it stings like hell when the poop comes out and now blood is coming out. BUT the blood it doesnt come out everytime i go like one day i will go no blood, the next day no blood, but then the next day blood will come out. I also think when i go the bathroom i am not emptying my system full anymore. What should i do? People say that i just need more fiber in my diet, cause i dont each much fruits or vegetables. Could this be the problem? IF it is fiber, how long will it take for this to take in effect?
