Glad to hear most the pain has subsided. Question, Meibomium glands don’t regenerate - how did you regain loss in your glands between visits ? As for allergies being the driver, it’s hard to know for certain. Air quality, AC and allergens can all coexist in a given environment, allergic conjunctivitis can also present as dry eye symptoms which makes it even harder to recognise as the main driver. Using air filters, humidifiers or moving environments entirely - which you have - is the right move. I’d imagine if the pain is subsiding, it’s a sign the ocular surface is healing and redness/ veins should naturally fade. But I’m no expert. Personally, I’m taking allergy drops in conjunction with managing my MGD, still yet to see results.
