How important is it to be the member of all these 'pain clubs'? I am already a member of AAPMR, ASIPP, ISIS and also NASS. NASS is very relevant for spine surgeons. I also love the spine journal. I am wondering whether to continue the membership of NASS for coming year 2006? It is pretty expensive just to continue the membership for purpose of reading only spine journal. What do you guys think? Thanks for your opinion.
