What usually happens after facet joint injections?

Did the pain go away: Facet joint injections are a diagnostic and therapeutic tool that is employed by pain medicine specialists. The goal is to see if your familiar pain goes away in the immediate period after the facet blocks are completed and should this occur, then a diagnosis of facet pain is made and if and when the 'original' pain comes back, there are appropriate therapies that can be employed accordingly.

Hard to say: Depends on your pain issue. Facet injections are helpful and can be long-lasting, however if your get short lived relief you may need to get evaluated for a radiofrequency ablation for longer lasting relief (greater than 1 year of relief is typical).
