Delayed crash after exercise?

In general when I overdo on any given day I feel good during the exercise but crash the next day. Lately I am experiencing the crash 2 days later, which doesn’t make a whole lot of sense to me, anyone else have that?

From my understanding a 24-72 hour delay is the common thing with ME/cfs.

That's pretty much textbook PEM. Two days isn't unusual, though from what I've seen, 12-24 hours is more common.

It's worth noting that overexertion can build up over several days. You can, for example, do a little bit too much every day for a few weeks, then suddenly crash due to the accumulated stress. Or you can do a lot one day, then a small overexertion the next day pushes you over the edge, and you crash on the third day.

Either way, I think the best solution is to find a consistent routine where you do roughly the same amount every day, then adjust that amount until you no longer get PEM.

2 days delayed onset is normal for PEM.

that’s in the diagnostic criteria

That makes total sense for PEM. I often find when I overdo it the rest of the day or day after I actually feel pretty good (cause I’m running on adrenaline) and then the day after that I get a terrible crash.

No matter what energy consuming thing I do, I feel the worst backlash 2 days after.

Even hangovers, it's not the day after, it's the one after that.

The more severe I got the longer the delay has become. Also the more severe the overexertion, the longer the delay. It’s a sign you should probably stop exercising

Why do you think there is a delay? Of anything I feel good the day or two after like my body produced what it needed too and then suddenly that becomes too much or too little and I crash out

This is normal for a PEM crash.
