<human>: I have recently had severe abdominal pain and lower back pain and my most recent stool is one i have never witnessed in my 19 years and there is no online help as it is harder to describe. they were almost light brown/yellow lumps with dark brown flakey attachments off them. No blood or other components off observation, no changes in food eaten or fluids. just as extremely odd circumstance than is still paining me.
<bot>: Hi. The severe pain in abdomen with low back pain with the stool you have described can be due to Colitis. The colon being behind the peritoneal structure -, its inflammation can give associated back-pain. Colitis can give severe abdominal pain due to spasms as it tries to push out the contents if it is infected or has some problem not normal to it. Stool: light brown/yellow lumps with dark brown flaky attachments off them can be due to an infection in the colon, can also be undigested food material. It can also be due to extreme defamation of the mucosa due to severe inflammation. I would advise the following :Blood-complete blood picture, kidney functions tests, blood sugar fasting and post-lunch, Urine-routine, microscopy, culture and sensitivity (before start of antibiotic)Ultrasonography of abdomen. Stool test-Routine, microscopy, culture and sensitivity, occult blood, cyst and ova to rule out any worms in the intestines. Treatment will be an antibiotic suitable for intestines, metronidazole, Probiotics and antispasmodic depending upon the investigations.
