Hey Pookie! How ya been? Yes I believe this fibro is pretty close to RSd. Sometimes, the RSD is so darn painful, I told my doc, that all I want to do is sleep, I'm depressed over all this. I want to keep to myself, I don't even want to see my older sons at times, don't want to even answer the phone. My son's are starting to understand, but then sometimes, when they stop by, when I am hurting so bad, I put a smile on my face and act like I'm ok, so they don't have to worry about me, because their dad is so very sick. His kidney's are bad now and he is still on oxygen, very sick. These diseases are just really bad. Can't concentrate, sometimes I have trouble with my memory and don't even remember where I left something?? Anyway, Pookie, so very sorry to hear about your entire left side. did your doc. say the RSD has spread? Please keep us posted on that. Fibro starts out slowly, then one arm foot leg may hurt, ache so bad. then the fibro hits the deep joints of all over pain soon, and by the time you go to the docs, he will tell you what you have. I have never heard of this disease, until he told me what it was and I googled it. And yep, I have all the symptoms of fibro. RSD hurts the worse, a close second is Fibro. I will keep you in my prayers for your pain. I am sorry you have this pain, pookie!! Love ya, sweet friend, ~Desi
