There are many energetic formations like that (tree related). Most of them are usually clogged and dried and don't even work anymore. Like how already dead dry branches suck the water from the still healthy tree for no real reason anymore but it takes the tree time to break and let it fall down.
And yeah most nerve connection or more accurately the underlying meridians that they should represent are usually being overtaken by other forces or entities and it takes time to fix them when you have "Nothing better to replace it with yet". You can even call the "flesh" a fucking parasite too. Takes time to clear it and master it. There is a reason why Tibetan masters turned into light and vanished without leaving a body upon their "death". This karmic vessel loses it's purpose after a while but before reaching that point... it's quite vital.
