Oral pain meds take time to work and can cause stomach upset. Injectable options (IV, intramuscular, or epidural) act fast and bypass the gut. The US pain management market forecast shows that injectable is the fastest‑growing route of administration, with a CAGR above 6%. Why? Because patients want rapid relief, and doctors want to avoid opioid pills that can be misused.

What's available? Corticosteroid injections for joint pain (effective but can damage cartilage). Nerve blocks with local anaesthetic (temporary). And ketamine infusions for complex regional pain syndrome (CRPS) and fibromyalgia — but they're expensive and need monitoring. The US pain management market analysis notes that the fastest‑growing injectable is calcitonin gene‑related peptide (CGRP) antibodies for migraine — they're given monthly by injection and have revolutionised migraine care.

But injections aren't for everyone. They carry risks of infection, bleeding, and nerve damage. And the effects may be temporary.

The message: if you have severe, focal pain, ask about an injection. But don't expect a miracle. Use injections as a bridge to get you through a flare, while you work on long‑term solutions like PT and lifestyle changes.
