Sewer gas after septic pumping

[wlsmith]

I had my septic tank pumped out. Since then, we have sewer gas around a bathroom sink, under the kitchen sink and, perhaps, in the dishwasher. Is there anything about having a septic tank pumped that could cause this?

Nothing comes to mind, I just can't think of how pumping a septic tank could cause you to have sewer gas issues.

Are the traps dry? Have you used any of the effected fixtures?

Taps are in regular use, so I assume they are not dry. Maybe relation to the septic pump is just coincidental. Or, do I need to check (or have someone check, more likely) the stack? Maybe opening the septic tank altered airflow in the stack in some way that caused some debris already there to resettle in a fashion that causes a blockage(?) I'm not really suggesting, because I know nothing about plumbing. I'm just asking.
