What should I do if I have lower back pain and abnormal vaginal discharge after inserting an IUD?

Patient's question:

Detailed medical condition and consultation purpose: Uterine IUD has dropped to the cervix
Current general condition: Abdominal pain, lower back pain, abnormal vaginal discharge. Please tell me what I should do.

Doctor's answer:

Generally speaking, there are two common side effects after getting an IUD inserted. The first is bleeding. The second common side effect is lower limb or lower back pain. The IUD placed in the uterus is considered a "foreign body" to the uterus, especially when the IUD is oversized or positioned low, the uterus contracts to expel this "foreign body," causing uterine contractions and pain, which clinically manifests as lower abdominal pain and back pain. These symptoms often occur in the early stages of IUD insertion and can be treated symptomatically with pain medication. Most women adapt to these side effects within a few months. If these two side effects are not resolved with treatment and symptoms worsen, it may be considered to remove the IUD.
