Finally figured out the problem- it wasn’t the drain at all, but the soap in the liquid soap dispenser had somehow turned bad. I didn’t use the sink for a few days and the smell went away, then as soon as I washed my hands, there it was again. I knew toothpaste, etc. can foul up a drain, but I wouldn’t have thought of soap. Guess other folks with this problem should double check EVERYTHING that goes down the drain.
