How to lance and drain a blister
Assess the blister before choosing to drain it.
Not every blister needs to be lanced. In fact, some experts recommend that you should only drain blisters that are exceedingly painful, in weight-bearing or high-contact areas, or larger than 0.8 inches (2 centimeters) in diameter.
If the blister is intact and manageable, try to keep it intact. Apply a piece of moleskin, adhesive felt, or tape.
