Well my "electric" days are long behind me but I would certainly never recommend that any person try acid for pain relief. I'm also convinced that no doctor would ever prescribe it for pain either...not even Owsley or Leary would do anything that foolish...of course they used to.
In my experience, LSD is a very powerful hallucinogen and I've known more than a few people who never quite made it back from their trips completely. I'll take brutal pain any day over becoming an acid-casualty WITH pain.
Just one ex-day-tripper's opinion though
