Mine have always gone down. They’ve either gone down or burst (and I’ve had bad experiences with burst ones…I’m pretty sure I’ve posted pics of my super-duper swollen ankle after a burst blister got infected once).
Just swab it with rubbing alcohol and wrap it in something. Should be fine.
Even if the needle is clean, you’re still opening it up to a chance of infection. So at least wash it twice a day and keep it covered- put a dab of Polysporin or Vaseline on the bandaid or whatever to keep it from sticking and help it heal better, whether you pop it yourself or it pops on its own.
I’ve never popped a blister on purpose. I’ve gotten dozens throughout the years from things like sharpening pencils, cooking burns, walking in shoes that didn’t fit, etc. They’ve always gone down after a couple of days and then reabsorb, you can never tell there’s been a blister in any of the spots.
Echoing what other people have said, I’ve been told to never pop a blister. I never wanted to, because I heard it would hurt. The only time I ever (accidentally) popped a blister was after some rounds of laser tag where I was shooting the trigger so much the friction created a blister. I didn’t even mean to, it was a blonde moment of “What is this bump on my finger? pick pick POP OWWwwwwww! :(”
The risk of popping on its own is the main reason to consider “popping” a blister. It is better to do it yourself than to have it rupture on its own. You can do it in a more sanitary way with less damage to the protecting skin.
I have never had the patients to wait on a blister. The blister is always in a critical area that will continue to be stressed so I need a proactive plan. I use alcohol on the needle and pop it in several places and drain it. Then I put tape over it and continue to put the stress back on it. After the area has settled down for a couple days or sooner, I cut that skin off. That raised skin is not coming back anyway.
I’ve always drained it if there’s any chance that spot is going to get a lot of friction during the healing process and the blister is very raised. I clean the surface of the skin and a needle, then go in at the margin of the blister near where it meets the skin, and gently push the blister towards the newly-created hole to try to drain out most of the fluid. If there’s a pocket left that doesn’t seem to want to drain, I poke another hole at the margin near that area, and repeat with trying to drain it. Then more cleaning around the holes, and a bandaid over top for a day or so, to keep it protected while the skin is still vulnerable there. Eventually you end up removing the skin on top as it fully heals.
Not finding a definitive answer here or anywhere else over a week ago, I decided to find out for myself.
On Friday, December 18, 2015, I reached into the microwave oven for a ceramic mug filled with boiling water. Although I’ve done so hundreds of times in the past at home without incident, there was something strange about the glaze on this particular Chinese-made “Starbucks” mug a a friend’s house, as it instantly caused a second-degree burn on the side of my right hand ring finger where it had pressed against the handle loop. It startled me so badly that I jerked my arm back, which caused boiling water to splash onto my hand, causing additional first degree burns. Within an hour, a large, painful blister had formed on the finger.
I did consider draining the blister after three or four days, but then thought, if I were careful and kept it wrapped with an adhesive bandage and change the bandage every other day, there was a chance I could keep the blister intact. I succeeded in doing so, and today, December 28, 2015, I’ve removed the bandage and the blister has shrunk to the point of being essentially gone. There is clearly a layer of dead skin that will need to wear away, or that I may need to trim away with scissors once it tears, but the tenderness in the area is pretty much gone, telling me that the skin under the blister has fully regenerated.
So, the answer is, “yes”, blisters do go away on their own, and it takes about ten days if they’re protected against damage.
