Hello! So, um, I m 16 and female, and lately when I pee I get a sharp pain in my anus and on my lower pelves just above my genitalia, and sometimes I get this pain when I try to sit down or when I walk (It s not really frequent but it happens at least once a day) and also last night this pain woke me up and only went away when I pooped (but that only happened last night, now even if I poop it wont go away and I ll get the pain while trying to poop as well). I don t know if this has to do with anything but I am sexually active, I ve only had intercourse with my boyfriend who is free of any kind of STDs and we always use a condom. I also have some stomach problems, I have/had gastritis, and colitis.
