There are two possibilities for a pimple on the skin of the eye: first, it is a wheals pimple with redness, swelling and pain, caused by bacterial infection, it is recommended to do hot compresses twice a day for fifteen minutes each time, use anti-inflammatory eye medication, pay attention to rest and a light diet, use medication and hot compresses on time, it will heal in a week or so, if there is a pus head, you need to go to the hospital ophthalmology incision to drain the pus, after the pus is discharged, continue to apply hot compresses, anti-inflammatory until healed; second, it is a chalazion. The chalazion can be seen or felt as a hard nodule but it does not hurt or itch. The blockage of the lid gland outlet causes the discharge of secretions inside, and the more it accumulates, the more it forms a hard nodule. There is no good clinical solution for chalazion, if it is more than the size of a soybean grain, it needs surgery to heal.
