A titled uterus can have a variety of symptoms including pain during intercourse, pain during perioRAB, low back pain, UTI's, and infertility. However, there are some gynecological problems that can also manifest in back pain (i.e. endometriosis, pregnancy, pelvic inflammatory disease, etc) and well as non gynecological problems such as kidney disease or kidney infections which some people interpret as a back problem before figuring out it's kidney related. You can consult with your gynecologist first to rule out any gynecological conditions that could cause pain.
However you also need to see your primary care physician and discuss your pain. He/she may recommend x-rays and if needed a referral to an orthopedic spine surgeon or neurosurgeon if you need further evaluation.
