Postpartum knuckle pain, bending difficulties and morning stiffness are mainly caused by changes in a woman’s endocrine system after childbirth, resulting in fluctuations in a variety of hormones in the body and dysfunction of the vegetative nerves. Patients may experience physical manifestations of joint stiffness and discomfort such as fear of wind and pain around the body. Female patients usually need to talk to their doctor about the problem at their obstetric review to find a solution, and if it persists without relief or if they are in doubt, they may consider visiting a rheumatologist.
