No that’s not really an issue… bone has, more or less, the same amount of salty water that the rest of your body has. Bone is a concern for x-series implants only because of potential for blunt force trauma to cause breakage.
How long ago was it installed, because many people commonly say “all the swelling is gone” but it’s actually not… it’s just smoothed out and hard to see… but even a small amount of fluid can cause 1mm to 2mm extra space between implant and top layer of skin, and with certain phones this can be enough to cause readability issues. Full healing, particularly with flex implants that require scalpel work or a lot of tissue damage to get installed, can take many weeks for most people… some months for others.
For x-series, this is bad for potential for damage reasons, but for flex this is generally ok.
