Pus pockets on the baby’s head are considered to be caused by local soft tissue infection. First of all, you need to go to the hospital for ultrasound to confirm the scope, size and depth of the abscess and to see how much pus is inside. In addition, check the blood routine and CRP to see if the infection index is high. If the pus inside the abscess is not much, the surface tension is not high, and there is no fluctuating feeling when you feel it, you can temporarily take oral anti-inflammatory drugs or intravenous infusion anti-infection treatment. If there is a fluctuating feeling to the touch and the ultrasound indicates that there is pus inside, it is recommended to actively cut and drain the pus, release the pus, leave drainage strips in place, change the medication on time every day, and then cooperate with intravenous infusion treatment, which will have the best effect.
