If I understand your post correctly, you're doing a scarf in seed stitch (?) and there's a hole further back? OK, if that's so it sounds like you've done something to create a hole, perhaps an unintentional yarn over.
Whatever it is it can be fixed without unraveling the whole thing. Among the free videos on this site, in the Knitting Tips section, you'll find a list of instructions for fixing mistakes. Look at the very first one - "Correcting a stitch without unraveling rows". It's a great video that will probably help you with your dilemma!
Good luck and happy knitting!
