I am about 26 weeks pregnant...?

Ever since thursday I have been expeiriencing some of the worse pain I have ever been in. I went to the hospital, they didn't run any test just told me it was round ligament pain. Now its sunday, I can hardly walk, I take a tylenol but it only relieves the pain slightly. The pain surges through my entire body and puts me in tears at times, idk what to do... I feel like if I go back I will be wasting my time because they didn't help. I am just desperate for an answer, round ligament pain makes no sense with how severe and worsening my pain is getting.
