The pus head cannot be healed without squeezing it out. In clinical practice, for tissue septic infections, it is not advocated to use the so-called squeezing to break the pus head, because there is a possibility that the squeezing process may cause bacteria to enter the bloodstream and aggravate the infection. What is usually used is to puncture the abscess site to confirm that it is an abscess, cut open the abscess at the most obvious fluctuation, make sure to reach the deep part of the abscess cavity to drain the abscess fully, and remove the inactivated necrotic tissue and strengthen the change of medication with the use of antibiotics. Once an abscess occurs it means that the local tissues are necrotic and if the pus is not drained, it will certainly lead to aggravation of the infection and even cause sepsis, which can endanger the patient’s life.
