Is there a 'right' way to hold a guitar?

Question: Is there a 'right' way to hold a guitar!?

i've been playing for a few weeks now & when i play songs with mostly power chords, i seem to get a cramp in the muscle between my thumb and my index finger (the hand on the neck)
also, i do not rest my palm on the neck!. could this be causing it!?
or is it just because i have not been playin long!?Www@QuestionHome@Com

My guitar teacher told me that you should position your guitar to make the neck upwards enough so you don't have to change the position of your wrists to play!. Requiring to have your wrist in an unnatural position can cause a handful of problems, carpel tunnel to name one, even though you probably won't develop this!. If you still can't get it right then I recommend a strap!.Www@QuestionHome@Com

well its a little of both, you must let your hands get used to playing especially power chords!. And you could try resting your pakm on the neck but if you dont feel right playing like that then dont
dont worry, i've only been playing fot 2ish monthsWww@QuestionHome@Com
