OH, MY ACHING FEET: FEET AND LEGS
Blisters

If the blister is not broken and it’s small, don’t touch it. The top layer of skin
will prevent infection. Just apply a bandage and keep the blister cushioned
from further friction. It will heal itself in a few days.
If the blister is large and painful, drain it after thoroughly cleansing it with
an antiseptic (use rubbing alcohol or an antibiotic soap). Heat a pin or
needle over a flame to clean it and use as a lance. Prick one end of the
blister, and squeeze gently to drain. Rub an antibiotic ointment like
Bacitracin over the blister and apply a bandage. Change the dressing
daily, or if it gets dirty or wet.
If the blister has broken and the skin rubbed away, you’ll need to carefully
remove the dead skin with cuticle scissors after a thorough cleansing with
rubbing alcohol or an antibiotic soap. Clean the exposed skin again with
an antibiotic soap (rubbing alcohol will sting!), apply an antibiotic ointment
like Bacitracin over the exposed blister and apply a bandage. Change the
dressing daily, or if it gets dirty or wet.

BLISTER PREVENTION:
Rub petroleum jelly on every part of your feet and wear heavy cotton socks.
This will cut down on the friction and prevent painful blisters from
developing.
