Uterine fibroids may cause back pain and swelling, for example, fibroids grow on the back wall of the uterus, the diameter is greater than 5cm or the fibroids are multiple and grow between the muscle walls, making the whole uterus increase in size beyond the size of 8 weeks of pregnancy, which may compress the nerves in the back and cause back pain and swelling, so surgery is needed to remove the fibroids and restore the normal shape of the uterus, the back pain and swelling will gradually reduce and disappear. The pain and swelling will be gradually reduced and disappear. Of course, it is also necessary to go to orthopedics for further examination, such as lumbar disc herniation and lumbar muscle strain may also cause such symptoms, and further examination in orthopedics is needed, and if necessary, lumbar spine MRI is done to help diagnose. If it is clear that the problem is caused by orthopedic problems, further treatment in orthopedics is also needed, which can relieve and cure the problem.
