Burrows aren't circular. The sensations are likely from thinking about bugs.

ps: I had a small 1 cm. circular burrow looking bite on top of my left foot. at nite I get sensations under the covers around my feet, and a scurrying insect inside my shoe (twice)
it was a massage parlor with lots of towels. could it have lingered all this time on my body, or pets?
Scabies mites only live for an hour or so off a warm host. December is way too far away for you to be concerned, if you don't have the symptoms already. Also, exposure means close body contact, skin to skin, either sexual or otherwise. You don't catch it from shaking hands, hanging coats next to each other, etc.
Take care.
