my left thumb is always feeling sore after playing guitar for a while, is this normal?
am i holding it in the wrong position or using the wrong tension?
I get it too, even if I play sitting down, but I tend to associate it with the fact that a few years ago my left thumb was stepped on, kicked, and battered till it swelled up twice the size (it sucks to be a goal keeper), ever since then it was never the same.
It used to get sore, but now not anymore. Yea, now it takes about 4 hours of non-stop playing to get my thumb tired, its usually the fretting fingertips that go first however.
yeah, so far i raise a bit, it seem to be better ....
and i find that i need to keep my guitar near to horizontal with the ground, if i keep it around 45 degree like some guitarist, my waist cant take it, will start to pain
