There are many causes of migraine in maternity: 1. It may be related to maternal mental factors, such as the patient being more nervous, overworked or emotionally anxious, depressed or excited after giving birth, too little sleep, too much strain because of taking care of the baby, frequent interruption of sleep, all of which can trigger the attack of migraine in patients. 2. 3. Patients may also feel wind and cold, which may cause pain on one side of the head, and if there is throbbing pain or pulsating pain in the back of the head, it may be a sign of occipital neuralgia.
