After grinding out the blisters, it needs to be treated in various ways, such as strengthening care, pain relief treatment, fluid pumping treatment and anti-inflammatory treatment. 1. Strengthen nursing care. Keep the skin around the blister clean and avoid excessive stimulation, so as not to cause the blister to rupture and induce skin infection. 2. Pain relief treatment. If the pain symptoms are serious, you can take some pain medication, such as ibuprofen extended-release capsules. 3. Fluid extraction treatment. For larger blisters, you can use a sterile needle to puncture and drain the fluid from the lower part of the blister to protect the wall of the blister, and you must pay attention to good disinfection after the operation to avoid infection. 4. Anti-inflammatory treatment. The blisters must be sterilized in time after bursting, and should be bandaged with sterile gauze. If there are signs of infection, erythromycin ointment can be used externally, and oral anti-inflammatory drugs if necessary. Please follow the doctor’s instructions for medication and do not self-medicate.
