My wife age 62 seeing her gynecological oncologist tomorrow morning. Last 10 days or so has been having an intermittent slight dull aching sometimes in very low back area, sometimes in low front area where bladder is, as if the achiness ricochets around from front to back then eases up for a day then returns. We thought maybe UTI but no fever, no discolored urine, no burning on urination, no sharp pains, no pains higher up where kidneys are. She has been pushing fluids awaiting her Dr. appt tomorrow. Will ask him about it, but any idea what it might be? We thought maybe low back muscle strain from crouching at awkward angle rather than UTI. Also, she had hysterectomy about 2 years ago due to uterine cancer, 5 lymph nodes removed as precaution, biopsy clean, each 3 month checkup shows no sign of cancer returning. Her weight is normal. 5 4 and 108 lbs. She eats well, no other symptoms. Thanks.
