The effects are still incredibly minimal at relatively small distances. Bear in mind that any black holes created wouldn't actually have a mass greater than Earth, and the difference in force caused by the inverse square law that we experience because of the length of our bodies on Earth itself is very tiny.

I just did a quick calculation and I got the percentage difference to be 0.00000625% using Earth's radius as 64000km and the height of a person as 2m. Hardly enough difference in force to tear you apart.
