Hi,
There are several possible causes for intermittent swelling of the left eyelid, including:
* Sty: This is a common cause of eyelid swelling and is caused by a bacterial infection of the eyelid glands. It usually appears as a red, painful bump on the eyelid.
* Allergies: Allergies to certain substances, such as pollen or animal dander, can cause the eyelids to swell.
* Sinusitis: Inflammation of the
sinuses can cause pressure on the eyes and eyelids, leading to swelling.
* Blepharitis: This is an inflammation of the eyelid caused by bacteria or an overgrowth of skin cells. It can cause
redness, itching, and swelling of the eyelids.
* Eye infections: Infections of the eye, such as
conjunctivitis or
keratitis, can cause swelling of the eyelids.
If the swelling is intermittent and comes on suddenly, it may be helpful to keep a record of when it occurs and what activities or stressors may be triggering it. If the swelling persists or is accompanied by other symptoms such as pain or vision changes, consult your eye doctor or general practitioner.
Take care. Hope I have answered your question. Let me know if I can assist you further.

Dr. Priyanka, General & Family Physician
