Whether or not a wheal needs to be drained is related to the size and fluctuation of the abscess. If the abscess is small and has no fluctuation, it usually does not need to be drained; if the patient has a large abscess with obvious fluctuation, surgical incision and drainage is usually needed to promote the abscess to subside. Blepharitis is caused by an infection of the eyelid glands, also known as blepharitis, in which the affected area may be red, swollen, hot, painful and other uncomfortable symptoms. If the blepharitis patient’s eyelid abscess is small, and there is no obvious fluctuating sensation, can be observed, not surgical incision and drainage for the time being. If the patient’s eyelid abscess is large and there is a lot of pus and fluctuating sensation, the patient can have a surgical incision and drainage, place a drainage strip, and change the drainage strip regularly every day, so that the pus in the abscess cavity can be discharged in time, and to promote the recession of the abscess. It is recommended that patients with blepharitis consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
