Congrats on the upgrades!
I installed an xG3 in the knife edge as well. IIRC I had 3 days for it to heal before I went back to welding school and was using my hand probably more than I should have. I partially contributed that to why mine wanders as well as playing with it really early. A lot of people have mentioned in the past that you should wait 2 weeks before messing with it, but I was too eager to start lifting random objects.
Anyways, it was stationary at first, then started moving on me. It has gone up the the bottom of the first knuckle, and back right up to the injection site. Like you said, it was uncomfortable when it was at the extreme end. The discomfort went away after some time and it I don’t feel it when it’s hanging out with my pinky. I do have a lot of meat in the knife edge though, so I have to pull out my earbud case that has a magnet and go fishing. The magnet in the earbud case is enough to find it and pull it back to a better position when I want to mess with it. I can squeeze the area and force it back down by hand as well with no discomfort, but the magnet is quicker and more effective.
My opinion would be to continue trying to trap it with the rubber band or a trimmed up tooth pick and med tape. If the discomfort doesn’t go away though, I’d consider relocating it. The name of the game is “upgrade” not “trade off”, or as best as we can get it lol
I’m not sure about re-traumatizing. I haven’t thought about that, but that’s an interesting idea! I’d be concerned about causing more scar tissue and weakening the sensing and lifting capabilities though.
I tried installing a second xG3 in the other knife edge, but as this was a self install, I wasn’t able to get through the tougher skin. I ended up moving to P1 on the top of my hand It’s great for lifting, but not so much sensing. I can still pick up fields here and there, but not as well as my other xG3 in the knife edge. It is a thought for a relocation site though depending on your use case. I know at least a couple people have installed theirs in P0. The webbing area is more sensitive for me than the top of the hand, so that might be a good spot as well.
Here’s where mine likes to travel:
