The tingling sensation produced during the process of fertilized egg implantation lasts for about 3-5 days and not more than a week at the most. The tingling sensation does not occur in all pregnant women, but only in a few women who may be affected by hormonal changes in the body during the process of fertilized egg implantation, causing congestion of the pelvic tissues and organs, uterine spasms, or increased neurosensitivity, which may lead to pain symptoms. Most of these pain symptoms appear or worsen after exertion and can be relieved after rest. If the pain is more severe or lasts for a long time, it is considered that it may be combined with other organic diseases, and appropriate examination and treatment are needed.
