There is no circumstance where student loans will grow when you are actively making scheduled payments on them. Your balance will decrease monthly if you make your normal payments. Just mentioning that for sake of clarity -- some smart people I know don't necessarily have a lot of personal finance knowledge. Your loans will only grow if you either default on them or do something like triggering one of the income-contingent payment plans (which are a lot less good of an idea than people usually think, BTW).
Unsolicited financial advice: go to the institution you deposit your paychecks in and ask about consolidating student loans. (Another option, if you've been diligent about building your credit history, is taking a CC cash advance for a year, or take an unsecured loan. I'm getting unsolicited offers for either "1% fee, 0% APR for 12 months, then normal interest" from my CC at BoA or "9% interest, no fees" for signature loans from Discover at the moment.)
