Probably a good idea to report it.
Boy, I feel for ya. I had a lot of pain and spasms that would keep me awake or wake me in 2003. That was not fun. Hope you get it figured out soon.
Since the MonSter made it's lovely appearance for me, I noticed that my arms go to sleep when I'm sleeping a lot. I don't have to be putting pressure or anything on them. It's not positional either. But luckily no pain.
