Can I wear 20-30 mmHg socks all day?

Community discussion from nursing, POTS, and travel subreddits suggests many people wear 20-30 mmHg socks during full shifts or long travel days without issue, but reviewers new to compression often find that range uncomfortable at first. If you're unsure, the consensus is to start with 15-20 mmHg and step up only if you need more support.
