How to tighten a loose stitch on circulars

[jyotimagic]

I've been reading through all the threads on tightening loose stitches, but they all seem to be about a stitch on the end or beginning of a row, so apologies if this has already been answered - just point me in the right direction. I'm knitting socks on Magic Loop and discovered I had a couple of baggy stitches several rows back. I thought I could just take up the slack and continue pulling it through each stitch until I get back to where I am, but it seems to take forever. Is there an easier way to take care of a big loop hanging on the inside?
