How Do You Pop A Blister Without A Needle?

by Rebecca Rushton BSc(Pod)

I was asked recently, how to pop a blister without using a needle. I’m sure there is more than one person out there wondering how to pop their blisters without the stock-standard recommended needle. So here goes.

 

Sterile

Whatever you use, make sure it’s sterile. Your options are either a hypodermic needle; or my personal preference, a scalpel blade (see video below from 4:20 min for technique). Both are individually packaged and sterile. Use them once, then discard into a sharps container.

Disinfected

If you can’t use one of these, the next best thing to do is ensure it is disinfected and clean by either heating it over a blue flame (not an orange flame - your needle won't be clean), bleach or antiseptic hand gel.

Type of needles

Just so you know, a hypodermic needle is better than a sewing needle. As I said, hypodermic needles are individually packaged in a protective sheath and are sterile. Sewing needles cannot be purchased sterile and usually not packaged in something safe and convenient. The hypodermic needle leaves a slightly bigger hole in the blister roof which helps more blister fluid drain and not heal over as quickly. A sewing needle leave a very small hole in the blister roof. You’ll be surprised how quickly the hole heals over.

Hypodermic needles come in protective sheaths making them very safe to carry and store once used, before disposing of into a sharps container.

 

Other implements

You can use something else sharp and unsterile, like scissors, a pin or a pocket knife. Heck, you could rip it open with your teeth if you like. But you’d be mad to because you’ll risk it getting infected. Some don’t rate blister infection as a big deal or they see it as unlikely. Sure, most blisters don’t get infected, but when they do, they can get nasty. Please read this article about blister infection and at least become informed on the subject.

 

Squeezing

Don’t try and squeeze it like a pimple, especially on the skin of the soles and around the toenails. This skin here is much thicker and simply, the skin probably won’t break. All you’ll do is traumatise the area further.

 

Wrapping up

Please just use a sterile scalpel blade of hypodermic needle. And use it just once then discard safely into a sharps container.
