You may still feel pain after a painless internal exam, but the pain is not noticeable and most pregnant women generally feel no pain.
Painlessness can block the afferent sensory nerves, blocking the sensation of pain, and has less effect on the motor nerves. It is not possible for painlessness to completely suppress the pain sensation, but it can greatly reduce the pain sensation, basically reducing the pain sensation by more than half.
Whether the internal examination is painful or not is related to their own tolerance and other factors, most pregnant women generally do not feel pain during the internal examination, and even if they do feel it, it is a mild pain, which is generally tolerated.
If there is obvious pain during the internal examination, you should tell your doctor in time for further examination and treatment according to the cause.
