The buzzing on my guitar is just getting annoying now, buzzing at the 7th fret on the A string and below, and below the 12th on the low E.

Now, I play lefty, so it's strung that way, so the action and intonation is way off. On the low E string, the string is 4mm high, on the high E, it's not even a mm up.

Would adjusting the truss rod help any, or should I just invest in a lefty acoustic?
