Help ID a 1950s–1960s SF short story from a classic anthology (read ~1974): harsh industrial drudgery vs boring idyllic life, red-hot poker cauterization after explosion

I'm trying to identify a science fiction short story I read around 1974, most likely in one of the big "best of" anthologies from the 1950s–1970s (e.g., Science Fiction Hall of Fame, Groff Conklin treasuries, Anthony Boucher F&SF best-ofs, Frederik Pohl Galaxy readers, etc.).

Key elements I remember:

- The protagonist experiences two alternating/unexplained "lives" with no clear reason given (no aliens, dream machines, time travel, or simulation tech explicitly revealed).
- One life is harsh, repetitive industrial/factory/mining drudgery (possibly on a non-Earth colony or mining planet; feels more "alive" or meaningful because of the struggle).
- The other life is idyllic, pastoral/family-centered (peaceful rural setting, loved ones, simple joys), but it's portrayed as too boring/static/lacking challenge or purpose. I think this might actually be his "real" original life that became unsatisfying.
- Toward the end, in the harsh/drudgery world, there is an industrial accident or explosion that severely injures one of his limbs (arm or leg).
- In a graphic, crude emergency scene, the wound is cauterized with a red-hot poker (or similar hot iron/metal tool lying around from the machinery/factory setting). This is a vivid, horrific moment (Ellison-like in its unflinching detail).
- The cauterization seems to anchor him back to one reality or force some realization about which life is preferable.

Other context that might help place the anthology:
Around the same time I read stories like:
- "Desertion" by Clifford D. Simak (humans turned into Jovian creatures)
- "Scanners Live in Vain" by Cordwainer Smith (cranching)
- "The Country of the Kind" by Damon Knight (probably misremembered as "Valley of the Kind")
- "Vintage Season" by Lawrence O'Donnell (future tourists watching catastrophes)
- "It's a Good Life" by Jerome Bixby
- A story with forced overconsumption (possibly "The Midas Plague" by Frederik Pohl, quotas like using up many pairs of shoes)

The tone felt psychological/philosophical with some dark/grim realism—possibly by an author like Simak (pastoral contrasts), Pohl (satire), early Ellison (grit), Knight, or similar.

Does this ring a bell for anyone? Even partial matches or anthology suggestions would be appreciated. Thank you!
