Hi, For the last 6 months I ve been having dull abdominal pain on the right side, also light back pain in the same area. With months the pain hasn t changed much, it has become slightly easier to point the location on my stomach, in the beginning i could show just the area. Sometimes it feels it has moved bit to lower abdominal, sometimes it feels like hurting just below my rib cage (most common in horizontal from navel). Also for last two months my bowel movements are loose and light or yellowish. I do not have to go too often, just 1-2 times a day. Also i have noticed that lately all my stomach is more sensitive than it used to be, sometimes hurts after some foods, sometimes slight heartburn . So far I had whole abdominal ultrasound, which was okay. Had some liver blood tests, also okay. What could be the problem? What tests should I do? Im female, 28, not taking any medications, no other diseases than endometriosis .
