Dear Mimi,
Sorry you are suffering. I've been treated for GA going on 3 years. Fortunately I have no pain. The 1st Dr I saw wasn't knowledgeable with GA and didn't know what he was treating until after 1 year he took a biopsy and referred me to a Dr who specializes in skin disease and not superficial/ cosmetic treatments.
Dr #2 prescribed
Tofacitinib 2% ointment 2Xs per day and I've been using for over a year. Some GA patches are no longer "active" others continue to be red and raised around the edges. These have subsided. Dr #2 has chosen not to prescribe drugs with so extreme side effects or laser treatment. Thankfully, my lesions haven't spread since using Tofacitinib.
Maybe you could research another Dr who is less invasive with treatments.
I do pray you find relief from your suffering.
