Placed "correctly" can impinge a nerve and it will never show on imaging. I had a neuroma that didn't even show on MRI. Took plastic surgery peripheral nerve specialist to find it with Scratch Collapse Test. I got the sucker taken out. I still have pain there, some of the damage couldn't be repaired optimally but it is MUCH better than it was. I can tolerate sheets now and it doesn't wake me up at night. Socks are still a struggle but they put direct pressure where the neuroma was. But since I live in Austin we only wear socks two months a year anyways.
