What are the causes of lower back pain after inserting a Mirena IUD?

Lower back pain after insertion of the Mirena IUD may be caused by non-disease factors, or could also be related to medical conditions such as chronic pelvic inflammatory disease or lumbar disc herniation. It is recommended to identify the underlying cause and follow appropriate treatment under a doctor's guidance. Specific analysis is as follows:

I. Non-disease factors

After insertion of the Mirena IUD, stimulation of the endometrium may lead to uterine contractions, which are normal physiological responses. These contractions may cause lower back discomfort or pain, but symptoms typically diminish or resolve over time.

II. Disease factors

1. Chronic pelvic inflammatory disease

This condition may develop due to incomplete treatment of pelvic inflammatory disease or recurrent inflammation. Inflammatory stimulation can cause ligament tension, local pressure, and impaired blood return, resulting in lower back pain. Physical therapy may help improve local blood circulation. If necessary, medications such as oral levofloxacin hydrochloride capsules, ofloxacin tablets, or clindamycin hydrochloride capsules may be prescribed.

2. Lumbar disc herniation

Increased pressure on the intervertebral discs leads to disc protrusion. Prolonged sitting, standing, or maintaining the same posture for extended periods can easily trigger lower back pain, aching, or soreness. It is recommended to maintain proper sitting and standing postures. When necessary, under medical supervision, medications such as diclofenac sodium sustained-release tablets, ibuprofen sustained-release capsules, or celecoxib capsules may be used to relieve pain.

In addition, other conditions such as muscle or ligament strain and skeletal abnormalities may also cause similar symptoms. If symptoms are significant, it is advisable to visit relevant departments such as gynecology or orthopedics at a hospital for diagnosis and targeted treatment based on examination results.
