wow. I am so sorry to hear you had pain out of control over the weekend. I am glad to see that you can drag yourself to the computer.
I don't know your dx, so I can't imagine exactly what is causing this unusually bad pain. The only thing I can do is free associate to a time before I got my correct diagnosis when a physical therapist said that my scalenes were "a mess" and he was going to really work on them to loosen me up. Well, it felt kind of like a good hurt while he was doing stretching and trigger point pressures and massage. But within 6-8 hours I started to stiffen up, and eventually had spasms so out of control that nothing would help for days. After a day and a half, my doctor gave me valium, and I remember that when it would wear off (for 3 days) I would go back to massive pain from spasms. However, if you say you felt fine Thurs. night and all of Saturday, it's hard to see teh connection. How long between the massage and the pain>
