Since I bought my '51, I've been playing guitar a bunch more. As a result, pain in my upper back has returned. I'm going to have to make an appointment with a chiropractor, methinks. I just wondered how most of you play (i.e. in what posture). Normally I play somewhat like Robert does in his videos with the guitar on my right leg. Unfortunately, this usually causes weird contortions with my back between my shoulders, resulting in pain and things being out of whack.

I'm thinking of switching to a more classical style with the guitar on my left leg and that leg elevated by a stool of some sort. I messed with it for a little while last night and today and it does seem to be easier for me. I've read that the stool can result in lower back problems. All I know is that I have to change something. Thoughts?
