Hi, Recently I ve been having lower left abdominal pain. My pain ranges from sharp, dull, and cramping sort of pain. The other day I d noticed some type of white substance in my stool before flushing. Visit the emergency room yesterday, to only tell me, I might had an STD. Okay how can they be so sure, when I was told to come back in four days for my results. Can you give me some other reasons what may be going on with me? Unless they are right. I hope not, because that means my partner of 8 years is sleeping around unprotected. Thank you, A concerned one
