Helllo. So recently I ve been having problems urinating and passing stool more so with urinating). Basically, it feel as if I can t relax the muscles used to release the waste. Also, sometimes. Also I ve occasionally gotten this really weird feeling in my anus/sphincter where it feels like the muscle intensely retracts ( the muscle you would use to hold it in). It seems to usually happen when passing gas and is kind of scary when happens. I ve also been having occasional aching around my lower back right above the tailbone. But that s about it. In a 23 year old male, and I have no idea what this could be. I ve pondered around the idea of constipation, but I ve had a few runny stools so it can t be that Please help
