Hi I am F,lar a character I liked out of Dragonriders of Pern ,I have had RSD Dx ed since 1969 its been a long strange trip indeed .I have RSD in all 4 limbs but Type 1 and 2 in feet and legs where as I have Trophic or type 3 or 4 if thats in your beleifs ,its really stopped mattering to me .But I find exciting that they found an APA Test can tell if you have Fibro which I also have but rarely ;like to admit around people with just Fibro ,none of us can know anothers pain I figure but RSD has gotta be up there ,I think the APA Test may still be in trials it was when my Rheumatologist usd it on me but if its not out yeyt it soon will be .I have had RSD sooo long ,sometimes its very difficult ,I hope this group is still in existence Gentle Hugs F.lar
