From sometime(almost 2-3 months on and off) I am having constant pressure on anus for bowels. Heaviness in lower abdomen, side and lower back (sometimes pain as well), restless legs or kind of muscular spasms in legs. Had issues with frequent urination and penial discomfort but there was no infection of any kind. Discomfort of this pressure increases after meals. I am not constipated. Stools are normal. CT scan of pelvic area and MRI of spine are normal. Please help me diagnose what this could be. Thanks
