Sudden lower right back pain, dull and constant, trouble urinating completely, constant feeling to go urinate, pain reduces when you stand up but hasn t gone away. This has been going on for about an hour and a half. As I m typing, I m noticing that the pain has subsiding but not completely gone. I had dinner at home and drank an adult rootbeer before is occurred, and I ve had a glass of water while trying to relax.
