The causes of postpartum joint pain, commonly due to degenerative joint inflammation and joint cold, etc., are as follows: First, degenerative joint inflammation: excessive weight bearing leads to faster joint degeneration, the patient’s weight increases significantly during pregnancy, and the pressure on the joints continues to rise, which can cause joint degeneration to accelerate significantly, and degenerative joint inflammation occurs, and the patient will have joint pain. Even after childbirth, joint pain can still occur. Second, joint cold: postpartum patients are hot, will not pay attention to joint warmth, easily cause joint cold and lead to joint synovial inflammation, the patient will have joint pain, swelling and limited movement. After local heat, rest and braking, the symptoms will soon be relieved and will not affect normal weight-bearing and walking. Therefore, postpartum joint pain is a normal phenomenon. The way to prevent pain is to strengthen the muscles around the joints, and to control weight and avoid cold.
