I just added 2 values to a pick list field 10 mins ago, and am refreshing and refreshing and still it doesn't show the values. I just logged in here, wrote this whole message, and finally now it has updated to show them. So almost 10 minutes hitting refresh at least 10 times before it updated. It's not my PC either as I use 3 different machines, they all do it, Edge, Chrome, etc. I've seen many other people complaining about this but curious how people deal with it.

Lee, Salesforce implements an aggressive caching policy for the LEX framework to reduce the turnaround time from the server which causes grave refresh issues when working with Lightning. Thanks to this simple setting (that I was totally unaware of) which can help you deal with this issue:
Enable secure and persistent browser caching to improve performance
Uncheck it if it's already checked.
You can find it under Setup-> Session Settings -> Caching section
