Most wheals that show yellow pus are indeed almost healed, while a few need to be incised and drained even if they do show pus. A granuloma is a suppurative inflammation of the glands of the lids due to a bacterial infection. Therefore, as the disease progresses, most of them will form abscesses, and will gradually heal after the purulent secretion is completely eliminated. The yellow pus head has been exposed, indicating that it has become pus, and most of them will break out on their own, or break out and flow pus from the conjunctival surface or break out and flow pus from the skin surface. A small number of patients with large abscesses, even if the pus head is broken, there may still be pus secretion is not completely discharged and there is a residual, or after the formation of pus head, but still did not break through, need to be incised as soon as possible to drain the pus. It is recommended that patients seek timely medical treatment and follow the doctor’s instructions.
