Is Chronic Pain Always Osteoarthritis or Can It Be the Nervous System?

Having spent over a decade in lower-league football changing rooms, I've seen first-hand how football culture treats pain: as a badge of honour rather than a warning sign.

Players often shrug off aches and niggles, feeling pressured to play on despite persistent discomfort. But what happens when that pain lingers months or even years later? Is it always down to osteoarthritis, or could the nervous system be playing a sneaky part?

In this post, I’ll cut through the vague advice you might hear ("just rest it"), explain the underlying mechanisms of chronic pain, and suggest practical rehab approaches. Plus, because footballers and fans alike are often wary of the topic of medical cannabis or mistrust official guidance, I'll reference the UK Anti-Doping (UKAD) stance and a private clinic pathway, so you're properly informed.

Football Culture and the Stigma Around Reporting Pain

Footballers, especially at the semi-pro and lower-league levels, are taught early on to “play through the pain.” Chronic aches get wrapped up in stories of toughness and mentality, leaving little room for genuinely reporting discomfort. Coaches sometimes see pain complaints as weakness or attitude problems, which only feeds into a cycle of silence.

But long-term, this approach isn't just unhelpful — it can be harmful. Years of ignoring nagging pain often lead to degenerative changes like osteoarthritis or complicated persistent pain states. It’s time we shift the conversation to honest assessment and active management.

Long-Term Outcomes: Osteoarthritis and Persistent Pain

When pain sticks around for a long time, many people and even clinicians jump to the conclusion: “it’s osteoarthritis.” While OA is a common outcome of joint wear and tear, it’s not the whole story when it comes to chronic pain.

Osteoarthritis (OA) involves the gradual breakdown of cartilage and changes to the joint structure. Great post to read It often comes from repetitive loading and imperfect healing after injuries.

Persistent pain can happen even when X-rays look 'normal'. That is where the nervous system comes into play — specifically a phenomenon called central sensitisation.

Key Mechanisms of Chronic Pain in Footballers

• Imperfect Healing: Injuries that don’t fully heal can leave tissues sensitive and vulnerable.
• Cumulative Loading: Years of training, matches, and microtraumas add up. Without proper recovery, structures degrade.
• Central Sensitisation: The nervous system becomes over-responsive, amplifying pain signals beyond what tissue damage would suggest.

Central Sensitisation vs Arthritis: What’s the Difference?

Aspect Osteoarthritis Central Sensitisation Cause Physical wear and tear on joint tissues Increased sensitivity of nervous system to pain Pain Quality Usually localized, linked to joint use/movement Diffuse, can be out of proportion to injury Imaging Shows joint space narrowing, bone spurs Imaging normal, no clear tissue damage Treatment Focus Joint protection, strengthening, may require surgery Desensitising the nervous system, graded exercise

It’s common for players to have a bit of both at once. That’s why blindly blaming “wear and tear” can delay the right treatment.

Persistent Pain Explanation: Why Does It Happen?

Our bodies are amazing at healing, but not perfect. When an injury happens:

1. Tissue gets damaged and inflamed.
2. Healing kicks in, reducing inflammation and repairing tissue.
3. Sometimes, the healing isn’t complete; scar tissue may form, pain sensors become extra sensitive.
4. The nervous system starts to amplify pain signals — central sensitisation — causing you to feel more pain than there should be.

Think of it like a car alarm that keeps going off even after the break-in is stopped. Your nervous system can stay "on alert" long after the initial injury.

Active Rehab: How Graded Exercise and Strengthening Help

The key to managing persistent pain isn’t just avoiding movement but doing the right kind of movement. Graded exercise is a way of gradually reintroducing load to the joints and tissues without triggering a flare-up.

• Start Low and Go Slow: Gentle range of motion and light activity reduce fear of movement.
• Progressive Strengthening: Targeting muscles around the joint to unload stress and improve function.
• Pacing: Balancing activity with rest to avoid flare-ups and setbacks.
• Education: Understanding pain mechanisms helps reduce anxiety and catastrophising.

In other words, active rehab aims to retrain the nervous system and support joint health simultaneously.

UK Anti-Doping (UKAD) Guidance on Medical Cannabis

With increased interest in medical cannabis for chronic pain, many athletes ask: “Is this allowed?” According to the UKAD official guidance on medical cannabis, cannabis and related cannabinoids are currently prohibited in competition due to potential performance effects and health concerns.

If you’re considering this treatment, it's crucial to understand the legal implications, especially if you compete or aim to return to football.

Private Clinic Pathway for Medical Cannabis

Outside of competition concerns, some private clinics offer pathways for therapeutic cannabis use, primarily for non-competitive patients with chronic pain who have exhausted other options. These pathways usually involve:

• Comprehensive medical assessment to confirm diagnosis and appropriateness.
• Evidence-based consideration of cannabis as part of a multi-modal pain management plan.
• Ongoing monitoring of benefits and side-effects.

However, costs can be significant and evidence is still evolving, so tread carefully and always consult an informed healthcare professional.

Wrap-Up: Don’t Ignore What Changed in the Last 6 Weeks

If you’re dealing with stubborn knee pain or any chronic ache, the first question I always ask myself — and you should too — is: "What changed in the last 6 weeks?"

Understanding recent changes in training load, injury, lifestyle or stress helps pinpoint whether your pain relates more to tissue damage like osteoarthritis or nervous system sensitisation. Armed with that knowledge, you can tailor an active rehab approach that actually works.

Remember:

• Pain isn’t just “wear and tear.” It can be your nervous system’s alarm system running hot.
• Playing hurt may feel like “tough,” but it often makes things worse long-term.
• Simple, graded strengthening and movement help both the joint and the nervous system.
• Medical cannabis is not a quick fix and has legal limitations, especially if you compete.

Your body deserves more than vague advice. It deserves honest, practical solutions that acknowledge the complexity of chronic pain. Time to listen and act accordingly.
