So, I had an electromyograph and nerve conduction test done on Tuesday.
When I say this, it sounds like I took a car in to figure out why the dashboard was full of warning lights. (I think. I don’t know how cars do.)
I’ve been through a lot of medical tests in my life, including spinal tapping and having to put my face in a machine that blasted soundwaves into my eyeballs and took pictures of my optic nerves. I have to say, nothing really drives home the point that we’re just perpetually faulty bags of electrified meat like an EMG and NCS.
The idea is this: If your nerves or muscles go all fucky, they can’t do electricity right. This is measurable. Like when an electrician uses a multimeter to check for shorts, a neurologist can stick electrodes on you, stimulate your nerves, and see what happens.
Of course, by “stimulate your nerves,” I mean “jab you with a thing that feels like the unholy spawn of a TENS unit and a cattle prod.”
If you’re lucky enough not to know what the hell a TENS unit is, it’s a transcutaneous electrical nerve stimulator. It’s often used in physical therapy. Basically, they place a pair of electrodes on the muscles that need doing, and hook them up to a battery. It makes you all twitchy and feels super weird, but I am assured that it is sometimes necessary and not just an elaborate practical joke created by bored physical therapists.
To be honest, the nerve conduction study wasn’t bad. The only part that actually sucked was when they had to test the nerves as they ran through my elbow. That felt bad, but also took barely any time to do. Afterward was a bit crap, too, since I was there because of a burning nerve pain down my arm. As you can probably surmise, jabbing a burning nerve with a tiny taser doesn’t do much to improve matters.
Hey, it’s diagnostic, not therapeutic.
The next part was the EMG. This, admittedly, made me nervous as hell. I’d never had one, so I looked up what to expect. Five minutes later, I was positive that the entire internet was fucking with me.
The EMG is similar to the NCS, only for muscles instead of nerves. The NCS sees how well your nerves send and receive signals, the EMG figures out what your muscles are doing about them. In more complicated terms, it measures the electrical potential your muscles create when they’re stimulated by either electricity or signals sent by your nerves.
Unfortunately, I made the mistake of reading about people’s experiences with EMGs. (Don’t do this. I was smart enough not to read about spinal taps before getting one, and it helped a lot with my anticipatory anxiety. I didn’t do the same this time around, and it sucked a ton.) Most described it as extremely painful — some to the point where they had to stop the test halfway through. Everyone responds differently to pain, and I have a fairly high threshold at this point, but I still felt really anxious about it.
Fortunately, between a very kind, reassuring neurologist with an excellent bedside manner, and enough tincture of chamomile to sedate multiple kaiju, it wasn’t too bad. After the NCS, the doctor came in, asked a few questions, conducted a physical examination, and then stabbed two inch needles into all of the muscles of my arms, one at a time, and had me try to move them while a machine blared static into my ear.
Surprisingly, it wasn’t nearly as bad as it sounds.
Was the static uncomfortable to listen to? Kind of, but it was also really cool. Needle goes in, static is quiet. Muscle moves, static gets louder. It was neat to actually hear the electrical stuff that goes on in a body. I don’t often go out of my way to remind myself that I’m just a sack of organized seawater and electric meat, so it’s kind of cool in an eldritch-body-horror-biological sense.
Did the needles hurt? Some of them, yeah. Most hurt less than a vaccination, and much less than getting an IV. A few areas, like the heel of my hand, hurt quite a bit. Fortunately, testing each individual muscle doesn’t take long. A few seconds, and the needle was out again. Weirdly, I barely felt the ones stuck into my neck or the back of my forearm. Go figure.
Did I bleed a lot? Not really. I am covered in those tiny little roundyboy band-aids, but that’s probably because I’m on sertraline and it tends to make me bruise and bleed a bit easier. The doctor mostly just put them so I wouldn’t end up with little bloody spots on my clothes and didn’t come out looking like I’d been roughed up by a gang of drunken biker wasps.
I came home, made lunch for my partner and myself, and got some writing work done. I did feel like I needed a nap in the afternoon, but that was probably the burnout from all of the anxiety I was experiencing.
Now, I wait and find out why my nerves are bad at electricity.
