When you get up from a nap and your left eyelid is swollen, there are two possible conditions: 1. Inflammation. The most common inflammation is blepharitis, or wheals, which is an acute, painful, purulent, nodular inflammation. First you can apply hot compresses for 15 minutes each time, three times a day. Next, you can apply levofloxacin eye gel and take oral anti-inflammatory medication if the swelling is severe. If an abscess is formed, you can go to the hospital to make an incision and drainage. 2. Allergy. At this time, the eyelids are swollen with itching. If allergies occur, you will have to do allergen testing and stay away from allergens afterwards, and you can also apply tobramycin dexamethasone eye ointment.
