The effect may be temporary or permanent, depending on the severity. In general, treating pain with a 5 KV power supply is what we would call "A Bad Idea".

content: Electric shock can be used to relieve pain. It's called transcutaneous electrical nerve stimulation.https://en.wikipedia.org/wiki/Transcutaneous_electrical_nerve_stimulationObviously this is done with a medically approved device, not something just thrown together, so don't attempt to do it yourself. The fact that the electric shock provided pain relief, was just lucky. Next time you might not be so fortunate.

content: Human biology is seriously weird!It seems that the shock somehow "distracted" your pain sensors from your original pain.I had something similar happen when I had a really nasty pain in my left shoulder blade, causing me to have some time off work.During my first day back, it returned (not as severe, but still annoying).As I was working, I was stung on the left ear by a wasp.The shoulder pain went away!

content: Quote from: mikerj on March 20, 2018, 09:53:56 amWe've had this discussion before.The meanings of words change through time, with the original meaning often differing from the current usage. Originally the word electrocute meant death by electricity, as it's a portmanteau of electric and execute i.e. death, but it's now commonly used to refer to pain an injury caused by electricity, i.e. an electric shock.

content: Quote from: Hero999 on March 16, 2018, 01:52:07 pm^ This. I've used T.E.N.S. machines before. Apparently they go from about 0-300V and can put out as much as 700mA. The one I used during physiotherapy had crude analog controls to vary what I assume to be the voltage and frequency/pattern of the shocks. You'd place two electrodes diagonally across the muscle group giving you trouble, and it repeatedly shocks the area. If you crank it up, it's certainly strong enough to cause rather large movements of large muscle groups. You definitely don't want to try to hold your cup of coffee with the arm attached to the shoulder attached to the TENS unit. Unless you want to smell like coffee for the rest of the day, that is.While it was a good bit of fun, it didn't really help my pain.Maybe 5KV would have worked better, but I prefer my nerves lightly toasted, not deep fried.

content: Quote from: Mechatrommer on March 20, 2018, 06:34:56 pmYeah, similar. As this was some time ago, the one I used was a simpler construction, entirely analog, and an approved medical device in Canada. But the principle is the same. Glad you've found a little relief... that can be very hard to come by.

content: Quote from: IanMacdonald on March 20, 2018, 10:09:53 pmThis is getting tiresome. You didn't read by previous post. Modern usage of the term electrocute, can refer to non-lethal injury.https://www.merriam-webster.com/dictionary/electrocuteI do agree that the original poster is exaggerating, as they weren't injured, just shocked.

content: Quote from: pranav.appu.472 on March 23, 2018, 10:26:31 amyou are forming voltage divider between your finger and the resistor, so voltage at your finger will not be much, hence current will not be much. now you can play with different R value until you feel similar to touching a 240V, and then you can work out how much effective R your body is. and then try again on wet barefoot

content: Quote from: tooki on March 23, 2018, 11:38:07 amthats called brainfart or lost directives in life, there is no way 2 unsynchronized clock produce synchronized motion. even if its true, it has nothing to do with TENS, it has something with brain damage, one is cortex M1 part the other part is sensible cognitive, i mean if you know you have such disorder, why keep doing stuppid things? either way, brain fart it is.

Hint, try different parts of your body part, must be interesting results to watch.Suggesting the upcoming video's title "Pranav ...The Capacitor Man", pretty sure this will generate lots of subscribers.

content: The word required here is "Endorphins" the electric shock caused them to be released, that is what a TENS machine does, also what a wasp sting will do. It is well known that bee stings bring down inflammation and some people even use bee stings to treat arthritis.

content: Quote from: G7PSK on March 25, 2018, 05:05:08 pmI've seen PTs do this on other people while in therapy myself after i got my hips replaced.. they actually used some medication with it and was pretty fascinating to watch. Apparently the electricity also activated the drugs along with the muscles being stimulated.

content: Yes, your body can act like a capacitor. Have you ever rugged your feet on a carpet and zapped someone with your finger or got a shock touching the kitchen sink?Although electricity can effect different people in different ways ,getting electrocuted should not be taken lightly.It can cause internal burning ,which can lead to permanent damage to muscle, bone ,organ ,vascular and nervous tissues. Best to see your doctor if you received a serious shock that leads to any discomfort ,pain or redness.If someone zaps you with static electricity from their finger.Zap them back.

content: Quote from: G7PSK on March 25, 2018, 05:05:08 pmNo - TENS is thought to work by spinal gating of pain (see my prior post for link) - not via widespread release of endorphins.
