Well, the answer is…it depends. Are you asking about getting an intramuscular injection of some type of narcotic? If so, the answer is yes but why would you want to inject it when you can take medicine orally and it takes just a little bit longer 15-20 minutes more to get results.
If you are talking about nerve blocks or epidural or facet injections…then no.
If you can give more details about what specific drugs or types of injections, please reply and I will try to answer again.
