Thank you all for the warm welcome. Thanks for explaining the nerve blocks and what you all been going through. You guys are much more worse than I am and here I am whinning. I have never in my life heard of this. I just found this out from my attorney. yes I am on WC and its nothing but frustration because I have to do all the test they request me too. Along the process i have to wait and wati for approvals which makes it worse for me. I believe they just want to dope me up and just call it a day. I refuse to be doped up. It never worked for me anyway so I just sit here in pay see the dr just to hear the same thing again..you have to give it time be positive. I can't work more less do anything active but walking. That is all I do. I can't do anything to myupper extremities. I don't have the discoloration but i believe i have swelling in my arms and hands...When i get it in my thighs im stuck in bed until i can move again. Ijust found this site by accident and i am glad I did. I feel so outof place since my issue is not as bad as yours make me feel bad. it seems you all are managing it pretty well. I hope i can get there soon Thanks again
