After the tubal examination, we should pay attention to proper rest, keep the vulva clean and dry, eat a light diet, avoid eating spicy stimulation and cold food, prohibit coitus and pelvic bath for 1 month, follow the doctor’s instructions to give metronidazole and other antibiotics to prevent infection treatment.
