My stomach has been hurting for the past two days, I have not used the bathroom in a few days,tonight my stomach started to hurt real bad, went to the bathroom and it was hurting so bad that I felt like I was going to pass out,when I finally use the bathroom it was not hard then it became like water the second time I went and had some blood in it,and it hurt so bad like a burning pain, the next time I went it still hurt and like water, and this time it was just a little and it was blood,and am sick to my stomach and some of my stomach pain has gone away since I use the bathroom,but I am scared, just got Thur taken some strong aintabodits for pneumonia, and I have COPD
