Why do interventional pain physicians avoid relying on opioids?

Opioids have a legitimate but limited role: acute pain after injury or surgery, short flares that need to be controlled quickly, and select complex cases where other options aren't enough on their own. Outside of that, interventional pain medicine approaches opioid use cautiously — an approach that lines up with current CDC clinical guidance on opioid prescribing — for one central reason: opioids change how pain is perceived, not what's causing it. A compressed nerve root, an arthritic joint, or a damaged tendon is unaffected by the medication; it's still there, doing the same thing, once the drug wears off.

The evidence for opioids providing lasting benefit in chronic, non-cancer pain is genuinely limited, and long-term use carries specific, well-documented risks:

• Tolerance — the same dose produces less relief over time, requiring escalation to maintain the original effect.
• Dependence — the body adapts physically to the drug, independent of whether addiction is present, making the medication itself a problem to manage.
• Diminishing effectiveness — many patients on long-term opioids report the pain relief plateaus or fades even as the dose increases.
• Overdose risk — risk rises with both dose and duration of use, and increases further when combined with other sedating medications.

A targeted interventional procedure — an injection, an ablation, a stimulator — is aimed at the pain generator itself, so relief doesn't depend on an escalating dose to maintain. That's the practical difference: treating the cause instead of managing the signal.

For patients already on opioids, this isn't a judgment — it's information. Dr. Foster evaluates whether an interventional option could reduce a patient's pain and, over time, their need for medication, coordinating with their other providers rather than making unilateral changes. Abruptly stopping a high dose carries its own independent risk, which is exactly why any reduction in opioid use happens gradually and in coordination with the providers already managing that medication, not on its own.
