Do you have access to a strong rare earth magnet? The ferrite core in the implant might just be tugged on enough for you to feel it. Especially if you’re moving the magnet back and forth over the implant.
edit
Just tried and no sensation, but the magnet does stick where the implant is, then I can hold my hand upside down and it won’t fall off.
just be sure to get a neodymium magnet … the brown/black type used for cheap fridge magnets are alnico and have a really bad field strength to mass ratio and will have a hard time sticking.
Thankfully I sort of see my DT glass implants when I make a “power fist”. They’re not coated, so they freely went into hiding soon after implantation. But if the thenar muscles push them out of their foxhole, they’re visible.
Same thing for the one in my foot: it’s taken a bit of a hike too (yes, I do have to make a sort “power foot” to see it )
As for the FlexM1, surprisingly, this one is the most inivisible of all. I know exactly where it is and it has nowhere to go, behind constrained on all 4 sides by two metacarpals and two ligaments. It’s not like I’m wondering if it has shifted. But it’s properly invisible, and it takes a lot of effort to make it push up the skin and reveal itself.
The one I worry about most is the flexNExT: it’s so easy to lose these things…
I checked my chips. The one I have where your Sparks are seems to be a tricky location to light up. I have laser pointer (the cat entertainer) with white LED in it.
I can see my FlexNT with it, but with the other implant I really have to dive it between the thump/index finger webbing to see the chip. Edit: and I’m a skinny guy.
Apologies on the delay i was having some issues with the viviokey app and logging into the forums So i did find it my DR said he could do an Xray at cost so i went that direction.
My next question how close to the bone can this be without issue? Its pretty close.
I believe the official answer is 5mm, that being said I’m pretty sure several people have implants that break that threshold and haven’t reported any issues yet, so I wouldn’t worry about it unless it’s bothering you, but hopefully someone more informed than me will reply with better info soon
