Strongly disagree. They are good at fixing a lot of things but my list of things that medicine is not good at treating are auto-immune issues, post-viral conditions and long-term pain from a variety of sources.

Edit: Sorry should have included: "and the brain"

Tell that to the two herniated discs in my spine :(

No good long term prognosis, they can't be replaced and the only things to be done only postpone further problems (steroid injections) or cause critical ones later down the line (disc fusion).

It's getting better. See "metabolic psychiatry" as an example.
