Hi Shoedog,

Welcome to the site and to the guitar!

If you had not injured your left hand in the past, I would say folks like you (i.e. new guitar players, lefty or righty) would eventually develop the stretch they need to make power chords, etc. with practice. And I would generally encourage a lefty to play a standard "righty" guitar, as both hands are required to learn to do a lot of things and playing standard guitar just makes life a little easier in terms of access to instruments, etc.

You may be a special case because of your injury. It's a great sign that it only took you a few days to work up the stretch for power chords, but it's impossible to say how and if that injury will play out as you continue to develop. Playing guitar may actually be therapeutic - or you may find you come up against some physical limitations that are a result of the injury.

I don't know if this is even helpful as I don't feel I can officially recommend one path over the other for you - but maybe this will help you think it out and decide which way to go based on your own instincts about your own hands.

Best wishes - Lisa McCormick
