Tingling in the pubic area at 39 weeks of pregnancy is mostly due to pressure from the descending head of the fetus, which is usually delivered in about a week. However, it may also be caused by vaginitis or perineal edema due to high blood pressure during pregnancy. The separation of the pubic bone may also cause perineal tingling, and this type of discomfort is not indicative of the time of labor. It is recommended that pregnant women go to the hospital for a checkup to pinpoint the location of the tingling, measure blood pressure, and perform a vaginal discharge test and fetal heart rate monitor to see if the fetal heart is responding well and to identify the cause of the pain. If a pregnant woman experiences tingling in the pubic area accompanied by pain in the lower abdomen, it suggests that she may go into labor in the near future, and she needs to undergo an internal examination and pay attention to the condition of the cervix. In primiparous women, the cervical opening gradually disappears and then widens, and in menstruating women, it disappears and widens at the same time. Tingling in the pubic area accompanied by redness is also a more definite sign of labor. Regular contractions will occur within 1-2 days of the redness, and attention should be paid to the presence of vaginal fluid. If the membranes have ruptured, hospitalization is required as soon as possible, as intrauterine infections may form after the water breaks, and therefore the absence of contractions for 2 hours after premature rupture of membranes needs to be treated with oxytocin. If a pregnant woman at 39 weeks has only tingling in the pubic area, no contractions, and no vaginal bleeding or vaginal discharge, it is not a precursor to labor. A vaginal discharge test should be done to note any inflammation of the vagina. If vaginitis is present it may cause a localized tingling sensation and may be accompanied by increased, yellowish, greenish leukorrhea and itching. To actively follow the doctor’s prescription medication, the most commonly used drugs are nitrofurantel mycotoxin vaginal suppositories, can be placed in the vagina to treat, usually need to be treated for about a week. Usually pubic bone separation caused by perineal pain, no special treatment, appropriate rest can be. If the perineal edema caused by high blood pressure during pregnancy further leads to pubic tingling, need to give antihypertensive treatment, if necessary, terminate the pregnancy.
