If the lack of sensation was from lack of blood flow, it would mean tissues were dead, and you’d essentially be fucked. You would already be seeing other symptoms, and they aren’t pleasant. The amount of sensation loss from restricted blood flow returns quickly, or not at all.

What you’re dealing with is most likely from nerve compression. Two days is enough to see a doctor and verify that there’s nothing major going on, but typically you’re looking at a gradual return of sensation over days to weeks. Thing is, if it isn’t returning as it should, delaying treatment is a pretty bad idea. There’s limits to treatment to begin with, but sooner is better than later, you dig?

It’s a thing. In bed bound patients, it’s common enough that I’ve seen it dozens of times. They get a leg stuck through bed rails, and a nerve gets compressed, and then they’re all pins and needles, or without sensation for a while. In facilities, it’s on the staff when they’re in that position long, but in home health, you’ll show up and the patient may not have had anyone with them overnight, and that’s when our can take time to resolve.

But when it’s blood that’s restricted, it isn’t just sensation that’s an issue. You get discoloration as well. If that color doesn’t start returning to normal relatively quickly as soon as the pressure is gone, you’ve got trouble. People can and do lose limbs that way. It can actually kill you if left in place; dying body parts are not good for the rest of you. But

You didn’t mention anything about the skin being blue, or worse colors, so it’s unlikely that blood restriction is what caused the issue.
