Does your stun gun have two prongs and carry a residual charge? There is a Black Cobra J-911 stun gun in each of our vehicles, as well as one in the vet box and one in the first aid kit for the sole purpose of neutralizing poisonous spider/snake bites. Now main stream medical says that stun gun treatment is not substantiated, but I know first hand by personal experience that it does indeed work.
I was bitten on the inside of my arm by a black widow spider while carrying fruit crates from the barn (yeah, I know, I should have checked under the edges of the crates first, vs seeing the spider after the fact). But what started out as a little sting developed into nauseating pain and red streaks going up to my shoulder and down to my wrist within 30 minutes. Now I could have followed the advice of main stream medicine and gone straight to the ER, where chances are I would end up sitting in the waiting room for an hour (typical wait) and then in the back for another couple of hours while the docs would try to figure out the best course of action, insisting on morphine to help with the pain in the meantime (I use to work in ER, so I know the drill). But instead.....
...a prepper friend of mine came to the rescue with his little Black Cobra stun gun. He turned it on, zapped it in the air, then shut it right back off. Then he positioned the prongs on my arm on either side of the bite and as soon as the prongs touched the skin, it discharged the little residual charge that remained. It felt like someone just slid their feet across carpet and then zapped me with the static electricity. He repeated the turn-on/air zap/shut-off/residual discharge process about a half dozen times, each time discharging the residual charge on either side of the bite, going in a circle all around it. Within an hour, the streaks had visibly diminished, the pain was noticeably less and I was no longer sick to my stomach. The next morning there was no pain, no streaks, just two tiny, tiny holes from the bite...and it itched. And by the following day, there was no sign of a bite whatsoever. That was it. I have had the unfortunate opportunity to personally test it again, but this time with a brown recluse bite. Again, by the next day it was like I had never even been bitten.
Now as I said before, main stream medical says that stun gun treatment is not substantiated, but it has been proven that on me it does work. And as such, we will never be without one. I can't say the same for the main stream medical treatment.
Just remember (and this is MOST IMPORTANT), if you are going to get a stun gun for this purpose, it must be one that has prongs and
be able to hold a residual charge. The Black Cobra J-911 is our stun gun of choice. Holds a nice residual charge and fits comfortably in the hand just in case you actually want to use it for protection purposes as well.
