Hands go numb, tingle from trackpad

You talked to the wrong person. You need to talk to a physician, not a physicist.

Yes, it could also be a good idea to talk to a physician. I wouldn't say a physicist is the wrong person to talk to though; I think it would be good to talk to several people with different backgrounds to help figure this out. Discussing the right term to apply to these wavelengths is very much in the realm of physics. I realized from him that I was using the wrong term of electromagnetic energy, and that static electricity may be more accurate. Besides, I have two physicists as my colleagues at work, so it was more convenient to talk to one during lunch about it. Next time I'm visiting my physician, I'll ask his opinion too, and how it may be affecting my body. Thanks for the suggestion.

But in the end, I still don't know the accurate way to explain these sensations; I'm not sure any of us do at this point, which is why we're still discussing it. It is all kind of fascinating to explore.

Me too. I haven't had my MacBook long and I thought I was going mad at first. I am left handed and my whole left hand tingles as soon as I start using my MacBook and it travels up my arm. My arm and wrist feel heavy afterwards. I tend to rest my left hand on the side of the track pad. It is tingling now as I write this. The other day my 6 year old daughter came up to me when I was on my laptop and every time I touched her we both could feel a weird electrical sensation. Ive never experienced anything like it before. She said 'What is that mummy?' I said I don't know sweetie, it feels like an electrical current'. It wasn't an electric shock, it was just a weird tingling/vibration electrical current passing between us. Very weird and very worrying.

That is indicative of improper grounding (or "earthing" ). It's generally harmless, though it does field weird. It's not uncommon in iOS devices. Does this happen with all outlets? Or just the one? If it happens with just the one, you may need to have it check by an electrician. If it happens with all, I'd take the MacBook and the charger to your the Genius Bar at your local Apple Store (make an appointment first) and have them take a look at it.

I'm having the same experience. It used to take longer for my fingers to start numbing and tingling when I use my Apple iPhone. I'm able to text less and less now. Once, my smart phone actually bit me. My fingers were hurting but I wanted to finish a game, so I ignored the pain. Suddenly, it felt like something reached out and grabbed my whole hand. It felt something like a numbness coupled with an electrical shock. It really frightened me.

It's not tennis elbow, nor is it anything that happens any other time. It's worse when I play games, so I'm thinking the amount of radiation might be higher in more complex screens.

Telling my doctor won't help unless he has experienced the same thing... all he will do is order a bunch of useless tests. It has to be the phone. It's not a health issue; it's an iPhone issue. The powers that be don't want to recognize the problem because they don't want to validate problems that will cause sales to drop. It's cheaper for them to wait and settle lawsuits when the phones blow up and someone is badly injured, or their house burns down. Any thoughts?

Nonsense. Has your doctor had every illness you've ever had? Does the fact that they have not mean they are unable to diagnose and treat? If that were the case, there's be a whole lot of male obstetricians out of work. It would mean oncologists who've never had cancer would be unfit to diagnose it. Tests that don't turn up anything are still useful in that they rule out things, thus narrowing down the possibilities.

If you're experiencing pain, you have a health problem. You can ignore it in favor of conspiracy theories with no scientific validity. Or, you can see your doctor.

At a guess (I'm not a doctor), the reason that your hands hurt more the longer you play a game is because you're using your hands more and for longer in ways that tend to result in cramps and overuse. The very small amounts of non-ionizing EMF radiation produced by consumer electronics cannot cause the sort of problems you're describing. At most, it will make your hands warm or hot as the phone heats up when playing games for long periods of time.

Sorry, but the glass surface can't explain this discomfort. I've covered my whole pad with a plastic sheet, but I still get terribly irritated. I'm an author and teacher, and spend most of my day on my laptop. This allergic response is making me miserable. The tingling (yes, that's the best word to describe it, like hundreds of tiny pinpricks all over the palms and fingers) gets worse at night, and I am truly at an impasse. I love my work, can't give it up. Can't afford a new computer. As soon as I can, though, good-bye Macbook Air! I've scoured the internet for a solution, haven't found it. If anyone has a solution, please, please share it!

The problem reads as though you're holding your arms lower than your hands.

same on my left hand..

did you get any help from apple?

i dont think they know this but i also think they are gonna ignore it..

what country do you live in? What kind of current and/or converter are you using for your Macbook? 😊

Take it into Apple. I'm sure they will take care of you.

look at one of the oringal posts I made in the forum..

It's funny, these complaints are specifically about the trackpad, yet I haven't found anyone complaining about the Apple external trackpad that uses the same components ;).
