Yes to both. I was diagnosed with rosacea a year ago but I have had the flushing ever since I got sick.
I had some pinkness above the bridge of my nose for a long time, but it has faded, and when sick early on had bright pink nose, cheeks, and lower forehead.
I've recent been bitten again, waiting for diagnosis now, and my face (esp. forehead) is very dry and flaky.
Might be hormonal for me, hard to tell.
