The wheals have become purulent, which means that the pus head appears, the surrounding redness and swelling subsides, and the abscess gradually converges, in which case hot compresses can be applied. Hot compresses can promote blood circulation, promote the wall of the abscess around the wheals, and the inflammation around it subsides, prompting the necrosis of the inflammatory material and the collapse of the pus, which is conducive to the next step of surgery. Because the cyst wall is formed after the abscess is collapsed, so that the inflammatory material is wrapped, it is easy to remove the purulent and inflammatory material cleanly when performing surgery, which will not lead to the spread of abscess or inflammation. It is necessary to use eye drops and eye ointment along with hot compresses to strengthen the control of inflammation and avoid spicy and irritating foods.
