Postpartum hives are mainly characterized by subjective itching symptoms on the skin. On the surface of the skin, you can see patches of varying sizes with a reddish color, some of which may also feel burning. Generally, this can occur within the first few hours and then quickly subside, but it is prone to recurrent outbreaks. Additionally, some patients may experience gastrointestinal reactions, such as nausea, vomiting, abdominal pain, diarrhea, and can even cause palpitations and difficulty breathing. When hives are detected, it is advisable to go to the hospital in a timely manner, and ask professional doctors to actively carry out examinations and treatments.
