Hello I've Been Having Severe Back Pain , Just a Day Ago I Had Thrown Up & I Have Been Really Nauseated.. My Mom Says I May Have A Kidney Infection.. The Pain Has Moved From My Whole Back To My Mid & Now My Lower Back.. I've Been Taking Vicodin Because I Thought It Was Just A Back Ache , I've Used Mineral Ice Gel To See If It'll Work But Nothing , I Can barely Bend Down & Can't Even Sleep Comfortably.. Should I Be Worried ?
