You might want to try doubling the amount of time for administration of the the Rocephin, it could be what we nurses call "speed shock" which happens when an IV drug is pushed too quickly.
If you're getting chills hours after the drug goes in, that's probably not it, I'm just throwing it out there.
BTW, chills are one of my herx signs. Could be that way for you too.
