Hello, yes they have tested her for a UTI more than once. Her doctor tested her negative several times, when she went into the hospital they tested her for many strains that came back positive, they've since resolved those with strong antibiotics. However, my mother is still experiencing the same symptoms. They suspect the lymphoma and plan to biopsy on Monday to determine the type. My mother had pelvic floor surgery in March and has been very sick ever since. They think the surgery caused the lymphoma to be inflamed.
