close - but in this case, it's something you eventually end up finding, resolving and the feeling goes away.

for example - as a developer, I have felt this before about single functions and sometimes entire codebases - I pay a lot of attention to my intuition - and I feel like it's part intuition, part paranoia, part anxiety that maybe you have rushed and done something wrong.

so - kind of like an anxiety resulting from intuition that you have made a mistake, and the feeling is reinforced by previous experiences - and it can be resolved by addressing the issue if you can identify it...

or maybe you sent an email like 5 minutes ago and get the feeling, then realize you forgot to attach a file
