I did read that you had PN, but have you ever heard of something called Erythromelalgia?

I have severe stenosis in the lumbar and cervical areas at multiple levels but I also have had a couple episodes of Erythromelalgia. My hands and feet got so hot I couldn’t shower (Unless I had a cold water shower) and I couldn’t seem to get them cooled down. It passed after a few days.

Just thought I would mention it. It’s something you can look up and see if it makes sense for your situation.

I do hope whatever it is that it resolves itself soon.
