Do Anti-Inflammatories Help or Slow Recovery?

Anti-inflammatory medications (NSAIDs like ibuprofen, naproxen, and diclofenac) are among the most commonly used treatments for musculoskeletal injury. They're effective at reducing pain and swelling in the short term. But the picture gets more complicated when you look at what inflammation actually does - and what happens when you suppress it aggressively.

Inflammation is part of healing

The inflammatory response after tissue injury is not purely a problem to be suppressed. It's a necessary phase of healing. Inflammatory cells clean up damaged tissue, release growth factors that trigger repair, and signal the surrounding tissue to begin regeneration. Blocking this response can impair the quality of healing, particularly for tendons and bones which have a complex inflammatory-dependent repair process.

What the evidence shows

Studies on tendon and bone healing consistently show that NSAID use in the early phases of injury reduces the quality and speed of repair. Tendon healing appears particularly sensitive - the collagen produced under NSAID use is less well-organised and potentially weaker than that produced without suppression. For acute fractures, NSAIDs are generally contraindicated for the first six weeks.

When NSAIDs are still appropriate

• Acute muscle strain in the first 24-48 hours, where pain control is needed to maintain movement
• Bursitis and synovitis, where excess fluid production is the problem
• Acute spinal pain with nerve irritation - short course, not longer than 5-7 days
• When pain is severe enough to prevent sleep or rehabilitation

Alternatives for pain management

Paracetamol provides effective analgesia without anti-inflammatory effects and is appropriate when pain control is the goal without wanting to suppress the healing response. Topical NSAIDs (applied to the skin) achieve local effect with far lower systemic exposure and are appropriate for tendon and joint pain as a compromise.
