My newly implanted xEM suddenly shifted backward half an inch, and now sits with one end almost right against my thumb’s metacarpal. I can pinpoint exactly when it’s happened, because I’ve been watching it closely since I had it implanted 5 days ago: it’s happened an hours ago while I was cycling back home from work. Before setting off, the chip was where I had it implanted. When I arrived home an hour later, it had shifted all on its own. No shocks, no nothing. It simply decided to take a hike.
I’m not really surprised though: for 5 days, it was more or less sitting on top of the thenar muscle where I had it implanted. But each time I would contract the muscle, it would rise on top of the bulge, and I could tell it wanted to slide down to the lowest point at the base of the muscle. And in truth, it’s much more comfortable there.
Also, I’m not really worried, because my other chip (not DT), which is about 1 cm away in the same hand and parallel to the xEM, has done exactly the same thing on the other side of the thenar muscle, with one end almost touching the bone too, and seems to be just fine where it is. It took longer to move because it’s coated in biobond, but it moved all the same, and quite dramatically too.
I could push the xEM back forward but I won’t for two reasons: firstly it’s reached such a cozy low point in my hand that it just won’t climb back up the muscle unless I insist to the point of becoming painful. Secondly, even if I did, it would drop back down again eventually, since DT chips aren’t coated with parylene. And I’m quite certain it can happily stay there forever with no ill effect, and it seems to be fairly well protected from accidents at that location.
Still, I’m curious about two things:
-
Can a chip actually touch a bone - without accidentally banging it against it that is - and if it does, does it matter? Is there some meat between the underside of the skin and the bone? Sorry if the question seems dumb, I ain’t no doctor, I’ve never studied anatomy.
-
How come both my implants slid away from their original implant locations so readily (particularly the xEM)? It’s almost as if the skin was only loosely bound to whatever is underneath and not holding anything in place particularly well. Yet considering how hard the piercer had to push to slide the needle underneath the skin, it would be surprising. So what gives?
Anyway, I guess I now have extra space for a third chip at the front of the thenar muscle if I really wanted one. An xLED comes to mind
On a side note, the oversized EM41xx chip in my other hand (not DT either), which was coated, and which I was very careful not to bump for a few weeks, sits exactly where I had it placed and is now firmly anchored, even with the muscle trying to push it out underneath. I wish DT chips were coated also, even if it means more butchery to get them out.
