For women who do not have the requirement to have children, they can often have a medical abortion or an abortion, and the back pain after a medical abortion is often considered to be a normal phenomenon caused by the stimulation of the uterus and pelvic cavity, which are still in a state of congestion. After a medical abortion, although the pregnancy capsule has been naturally expelled from the uterine cavity, but because the meconium tissue is not completely peeled off, and the uterus and pelvis are in a state of obvious congestion, so it will reflexively cause discomfort such as lumbar pain, and some women will also have obvious abdominal pain due to uterine contraction, especially after taking drugs to promote uterine contraction, this pain will be particularly obvious. This pain is especially obvious after taking medication to promote uterine contraction. If a woman does not rest after a medical abortion, the symptoms of back pain will be significantly aggravated, so it is necessary to rest for a week after the medical abortion to promote the recovery of the body, in order to avoid poor rest, which can cause back pain, or lead to poor contraction of the uterus, causing prolonged vaginal bleeding, or even poor contraction of the uterus, which may lead to incomplete medical abortion. If the symptoms of back pain are obvious, you can consider using hot towels or hot water bags on your lower back to relieve the pain, and if necessary, you can also apply pain relief creams for symptomatic pain relief. As long as there is no persistent pain in the stomach, but simple back pain, then there is no need to be particularly worried, but try to rest more, if there is no improvement after rest can go to the hospital for further examination.
