I am having a bit of an issue with a sore back when I practise. I'm on an acoustic, and sit the guitar on my left leg, playing righthanded whilst looking at my left hand to make fret movements. I am trying to sit front on with both feet on the ground but my back gets so sore only after 10min or so.....
Is this a common thing? Will it go away?
p.s. I have no pre-exsisting back injuries or problems, this thing is a one off..
