Eye swelling after chemical peel 3 months ago - what can be done?

I had a chemical peel done Feb 2021 under gen anesth. The peel included the eyelids and undereyes. Post treatment was wnl; however, approx 2-3 mo post L eye swelling that OTC and RX anithistamines no longer help. I went to an allergist and was told I had no allergies. It is becoming debilitating.
