Whether the blisters of herpes zoster can be punctured depends on the specific situation:
1. Generally, it is not recommended to puncture: It is generally not recommended to artificially puncture the blisters of herpes zoster. Because blisters contain a large number of virus particles, artificial puncture may lead to local secondary bacterial infection, turning into pustules, and may also leave scars after recovery. The course of herpes zoster usually lasts about 2 weeks, and the blisters gradually dry up, scab, and then fall off on their own, which is a natural recovery process.
2. In special circumstances, suction may be considered: If the blisters of herpes zoster are very large and accompanied by obvious swelling and pain, affecting the patient's daily life or activities, it may be considered to use a sterile syringe to suction out the blister fluid under strict aseptic disinfection conditions. After suction, antibacterial drugs such as iodine or fusidic acid cream should be applied locally to prevent infection. But this operation should be carried out by professional medical personnel to avoid infection or virus spread caused by self operation.
3. Avoid self treatment: Regardless of the size of the blister, it is not recommended for patients to puncture or treat it on their own. Because self treatment may increase the risk of infection and is not conducive to the recovery of the condition. If there is a blister rupture or infection, seek medical attention promptly and receive treatment under the guidance of a doctor.
The blisters of herpes zoster are generally not recommended to be punctured, but in special cases, they can be suctioned by professional medical personnel. Patients should avoid self treating blisters to avoid worsening the condition or causing adverse consequences.
