Hi SPED,
I'm sorry you were diagnosed with Fibro today. That breaks my heart. I have Fibro - bad. I know what you're dealing with here....
The red cheeks are exactly what Lynnwood said they could be too. If your lupus panel of blood tests came back fine, you're probably dealing with something very benign. I have never had the lupus rash (which made my diagnosis of lupus a lot harder to make), but I do have a slight redness to my cheeks most of the time. Nothing over the bridge of my nose which is classic lupus butterfly rash.
If you're concerned, take a picture of it. That way you have some evidence to show your rheumy.
Blessings,
Ginny
