You ever injure yourself from sleeping and sitting wrong?

This started out as funny to me but now it has been going on for far too long to be humorous anymore. About a month ago I slept "wrong" and woke up with a rather bad pain in my upper back. My arm was numb from the odd position I had managed to fall asleep in and i just figured it would go away after a little while.

Well here we are a month later and the problem is still there. I have gone to great lengths to try to stay off of that particular part of my back when sleeping and also try to enforce good posture in the rest of my day. I notice it most when I am sitting at a computer typing, which like most people is what I do for a job.

I think that almost all of us have pretty terrible computer posture and I have tried to correct this about myself. Unfortunately my current living arrangement doesn't really allow for me to have a comfortable chair with good back support unless I go out and buy one. Since I am not sure about how much longer I will be in this country that seems like a huge waste of money to me.

As far as the "sleeping wrong" aspect of my life is concerned I am reminded of Jim Gaffigan's standup comedy where he says "you ever hurt yourself from sleeping? That's a vigorous activity worthy of injury isn't it?"

It really doesn't make any sense but I guess this is just part of getting older. I have a bunch of pillows but I never really thought I would get to a point in my life where I needed a strategy in order to not have back issues from something like sleeping.

I've lived a relatively active life too so we cant' really blame this on lethargy.

So I guess you could say that I am curious if there are lots of other people out there that experience this phenomenon. There has to be a load of people out there with the same experience because I can't be doing it that wrong now can I?

I think I am going to start to get a bit worried about the future and the aches and pains that I have in store for me down the road. I don't like that this is happening but I guess this is part of being in your 40's. I've liked almost everything else that has happened up to this point but if there is more of this in the future for me, I am not happy about it!

What's the solution? Is there one?
