Suggest Treatment For Severe Pain And Pressure In The Stomach

I have severe pressure and and pain in my stomach with the constant urge to have to pee. When I go I m not completely empting my bladder because 1 minute later I have to go again. Sometimes only a little comes out and other times it leaked an I can t get up. Even though i just went i feel like i have to go again and the feelings uncomfotable And When I go I have a feeling inside me that I m not done peeing but nothing comes out and have pain in my stomach and pelvic. I don t have a uti and i was give a few pills for stomach spasm at urgent care but its not helping at all. What do I do. This is really annoying and haven t been able to sleep.
