If the anal swelling after abortion is not particularly obvious, it may be a symptom of painful uterine contractions. If the anal swelling is obvious or even feverish, it may be a pelvic infection or systemic infection after abortion, and you need to come to the hospital for relevant examination. If you don’t keep warm, get cold or do heavy physical labor or don’t take rest after the abortion, you may also have symptoms of anal swelling, which may affect the recovery of the body or the uterus after the operation. Try to rest in bed after the abortion, and if the anal swelling is obvious, it is best to come to the hospital as soon as possible.
