UTI help

Yesterday (wednesday) I was told I have a uti and was given the antibiotic and other medication to help with the burning. Now it’s over 24 hours. I take the pill(s) as prescribed and things just feel like they’re getting worse. I have sharp stinging cramps in my pelvic area also lower back and I’m super nauseas, also I’ve been sweating like crazy. Is there anything I can take along with the pills I have been given to help?
