@cbartonsandiego Yes I have one that hooks up to my iphone, it's called FLIR ONE. It's specific to either android or Iphone, I believe.... and it's not showing nerve damage, per se, it's showing temperature which is and indication of blood flow, which of course the nerves need.

you in San Diego? I lived in El Cajon my entire adult life, retired in 2018 and escaped CA in 2021.
