I have l.abdominal pain more to the left when i sit it feels like i'm sitting on a ball by my anus how ever there was blood in my urin, and still have l.back ache there is a slight burn when i urinate still. urinate test came back clear ?

More workup: Hi, there are a still few diagnoses to consider here, even with the "clear" urine test. I would recommend that you continue the discussion and work up with your doctor. Burning sensations with urination, combined with other symptoms can still be suggestive of a urinary tract infection, please don't put this off and follow up as soon as you can. Hope this helps
