Hi, lately every time I have consumed any kind of coffee, I experience a pain in my upper right back, and stomach cramps. It only appears after I have consumed coffee. But today, after not having coffee for two days, i went to the bathroom and found bright red blood in and around my stool. I was wondering if this could be something serious and whether I should be worries. I have had hemorrhoids in the past, but never experienced any pain/cramping with them.
