Can you recover from mercury poisoning?
Yes and no. If the symptoms just started and you haven’t been exposed for years and years, it’s very possible that those symptoms will dissipate. If it’s occupational — you’ve been exposed to this for many, many years and you’ve physically damaged the nervous system — that may or may not reverse.
