Thank you very much for the link to the pictures!
Both my daughter, 41, and I, 71, probably have lichen planus. I have had the ridged thumbnails periodically for ages; she has had terrible changes to her toenails, that she calls a fungus. We both have a horrible itching on the vulva, that in my case looks like the pictures of lichen planus.
She wouldn't really want to own to a diagnosis of Sjögren's Syndrome right now, as she is in denial about anything "wrong" with me, including the aftermath of being hit by a car. She also has had blepharitis, and ocular rosacea.
She *will* admit to acne rosacea, so I'll send her the information I have from the ophthalmologist on acne rosacea, and the study she's doing -- and your link to Google images.
