Dear Homeless,

I had the same problem, until I figured out I was pressing down too hard with my left hand (see Midchuck's message above). However, I did find that putting a cupla ice cubes in a plastic bag and holding it on my fingertips for a few minutes after I practiced helped a lot with the soreness. Also, can you adjust the bridge on your guitar? If you can, you might want to lower it, as well as lightening up on the pressure on the frets.

Good luck to you, Áine
