An epidural might affect one side of your body more than the other. An epidural might decrease your blood pressure, which might slow the baby's heart rate. If the anesthesia affects your chest wall, you might have the temporary sensation of difficulty breathing. Because epidural anesthesia can block the ability to empty your bladder, you might need a catheter. Fever and itchiness are possible. Even if you have a walking epidural you might need to remain in bed during labor. Rarely, you might have a severe headache when you're upright in the days after delivery.
