My left eyelid is swollen and puffy. Is there a home remedy for this?

Allergies . Allergies cause swollen eyelids. Cold compress can relieve the swelling. Over-the-counter allergy medicine, such as loratidine (claritin) & eyedrops help relieve it. Zaditor (ketotifen) is a good eye drop for itching. If it persists or gets worse go to your doctor. Another cause could be a blocked sweat duct around the eye. In that case patients respond to warm compress. It could also be other problems.
