I'm sorry for doubting you, I just see a lot of people claiming to have a phobia and laughing about it. It's like when people say 'lol that's so ocd of me'. I'm really sorry about your situation, I hope it improves.
So if you touch your stump in one place, it might feel like it's coming from another place on the stump? Or can the nerves still acurately tell where touch is coming from, even if they are criss-crossed? If I may ask
(Is that the holes fear)
