Ripping out= uneven rows HELP!

I’m knitting the Juno Regina shawl and have come to a major problem in the body. I started to rip out to fix a stitch and now my rows are uneven. This shawl is knit in sections and they now have a sort of ladder effect to the middle of the shawl- each section is a couple rows longer than the one before. I have ripped back many rows and can’t get it to even out. What can I do? Do I need to just use any stitch and knit in each section until it equals another? As soon as it’s even, would I knit back so that I begin in the pattern again?

This shawl represents weeks of work already and I don’t want to have to rip out the whole thing. Help!

If you ripped out entire rows, they should be even when you put it back on the needle. If you only ripped out partial rows, you may need to rip back complete rows, especially just before the laddering. If you undid some decreases then you have loose yarn that didn’t get worked into the surrounding sts.
