Good for you, Potts!
That's what these online support groups are for - support! Sometimes we need a little encouragement when it comes to dealing with the medical community, even when we know in our hearts and minds what we need to do. I've found that the very best source of information about a medical issue is to go directly to the source - the people who are living with the issue. Luckily for me, I learned that when I joined La Leche League when I was learning to breastfeed my first baby - nearly 33 years ago.
That is exactly why I sought out this group when I was told "possible Lupus" and I found the support group for AVN when I got that dx.
I'm glad that your kids' doc is a good one, and now you are headed for a rheumy. Is the kids' doc a pediatrician, or is he a family doc, so that you can keep him as your PCP?
