Some of these pop very easily, and some are waxy or hard. If there's no
redness, pain or swelling, they're ok to leave alone.

Lashes fall out all the time, without leaving blisters. If it got infected,
there'd be redness, pain, swelling or discharge, probably not blisters.

Some infections produce blisters ("fever blisters") but they aren't quiet
little 2-mm bumps.

Normal blisters do occur. The epithelium is aggressive and occasionally
covers tiny glands.

With heat and moderate massage you might make it break open. That's the
natural course. Popping it with something sharp isn't a good idea.

If there's redness, pain, swelling or discharge, beat a path back to the
doctor.
