Most of the symptoms of back pain after abortion are normal. During the operation, the stimulation of surgical instruments will cause uterine spasm and uterine contraction, and also increase the probability of pelvic congestion, so abdominal pain and back pain will occur under the stimulation of these conditions. It is more obvious in the 1-2 days after the operation and will gradually improve later as the body recovers and rests. During this period, you should pay attention to rest and not to overexert yourself. It is not recommended to do strenuous exercise within 1 week after the operation, and you should pay attention to hygiene to prevent infection. After the abortion, the resistance is low, so pay attention to the prevention of infection, so as to avoid the vaginal or pelvic inflammation due to the lack of hygiene after the operation.
