Hello, I am a 22 years old college student and recently my stomach has been bothering me non-stop. The last few weeks I feel like I cannot control my stomach. I always feel my stomach is turning and makes noises. Now i have noticed (twice/three times in the last two weeks) that sometimes there is a little blood on the bathroom tissue. Since then my butt (sorry for the lack of better words) has been itchy. I play basketball and lift weights so i thought it was just maybe from sweating so much but i have no idea. The itch started there and now seems like its spreading in the groin(even in my penis). I really have no clue what it can be. Please and insight would be very helpful. Thank you
