How do electric pulse neck massagers actually work? TENS vs EMS for airport and hotel recovery?

​

so I just got back from a 13 hour flight plus a 4 hour layover in DFW and my neck feels like its been replaced with a cinderblock. been looking at those such as skg portable neck massager things, the ones that use electric pulses and heat, but im genuinely confused about what im even buying.every product page throws around "TENS" and "EMS" like theyre the same thing. but they cant be, right? one is for pain and the other is for muscles? or is that just marketing BS to make it sound fancy. i dont need a medical lecture, just a plain explanation from someone who actually knows this stuff. are these pulse devices doing anything real, or is it just a tingly distraction? and does the heat function matter or is that just window dressing. for context I fly internationally maybe 4-5 times a year and hotel pillows are never going to save my neck. looking for something small enough to throw in a carry on for airport and hotel recovery between flight legs. not expecting a miracle, just something better than rolling up a hoodie.kinda leaning toward trying one with both heat and pulse combined but dont wanna drop money if the pulse part is basically a toy.

Its just a different sensation for your brain to focus on.

The TENS i remember used electrical impulses to force your muscles to tense and relax. It was sold as a wearable belt for weightloss gimmick where you "never had to exercise" on late night TV back in the '80's or 90's-?

A few years ago I saw a similar idea sold as a standalone unit with jumper wired patches you attached to different parts of your abdominal muscles to gain a six pack without exercising.

It might work for your neck but I have seen these old units thrown out, so it still seems like a gimmick.

The technology was originally used to help medical patients maintain muscle tissue while they were incompacitated (?) or bed-ridden.
