I've recently started learning some lead guitar lines, running through scales, modes, patterns, and my little finger simply will not do what I want it to. I have had a few breaks over the years (ring & pinky) and this does seem to have caused some serious problems. There's been swelling & pain since I started this program of intense practice, and while i expected to go through some of that, it does seem excessive. Are there any exercises I can do to bring my pinky into line with the others?
