Joints Still Ache? Why Voltaren Gel Fails & Medically Approved Next Steps

If your joints still ache after using Voltaren gel, you're not alone. While many people get relief from this popular topical treatment, others find their pain lingers — or even worsens. The good news? There are clear medical reasons why this happens, and there are proven next steps that can help.

Let's break it down in simple terms.

What Is Voltaren Gel — and How Does It Work?

Voltaren gel contains diclofenac, a nonsteroidal anti-inflammatory drug (NSAID). Unlike oral NSAIDs (like ibuprofen), Voltaren gel is applied directly to the skin over a painful joint.

It works by:

• Reducing inflammation in nearby tissues
• Blocking chemicals in the body that cause pain
• Providing localized relief with less systemic absorption than pills

It's FDA-approved for osteoarthritis pain in joints such as:

• Knees
• Hands
• Elbows
• Ankles
• Feet

For many people with mild to moderate arthritis, it can help reduce stiffness and discomfort.

But it's not a cure — and it's not effective for every type of joint pain.

Why Voltaren Gel May Not Be Working

If your joint pain isn't improving, here are the most common reasons.

1. The Underlying Condition Isn't Osteoarthritis

Voltaren gel works best for mechanical, inflammatory pain from osteoarthritis. It may not help much if your pain is caused by:

• Rheumatoid arthritis
• Gout
• Psoriatic arthritis
• Infection
• Autoimmune disease
• Tendon or ligament injury
• Nerve-related pain

Each of these conditions requires different treatment. If the diagnosis is wrong, the treatment won't work.

---

2. The Inflammation Is Too Deep

Topical diclofenac penetrates only so far beneath the skin. It works best in superficial joints like fingers and knees.

It may be less effective for:

• Hip arthritis
• Deep shoulder pain
• Sacroiliac joint pain
• Spine-related pain

In these cases, oral medication or other therapies may be more appropriate.

---

3. The Dose or Application Is Incorrect

Many people unintentionally underuse Voltaren gel.

For it to work properly:

• It must be applied four times daily (unless otherwise directed)
• The correct measured amount must be used
• It should be gently rubbed in completely
• Hands should be washed after application (unless treating hands)

Inconsistent use can lead to minimal benefit.

---

4. The Joint May Be Actively Inflamed

If your joint is:

• Red
• Warm
• Swollen
• Very painful
• Stiff for long periods in the morning

You may have an inflammatory arthritis rather than wear-and-tear osteoarthritis.

If you're noticing heat in your joints, it's worth checking what might be causing it — you can use a free AI-powered symptom checker for warm joints to get personalized insights in minutes. Warmth can signal active inflammation or, in rare cases, infection — which requires prompt medical evaluation.

---

5. The Condition Has Progressed

Osteoarthritis can worsen over time. When cartilage loss becomes more advanced, topical treatments may no longer provide sufficient relief.

Signs this may be happening:

• Pain at rest
• Night pain
• Decreased range of motion
• Joint instability
• Increasing stiffness

At that stage, stronger or more comprehensive treatment may be needed.

Medically Approved Next Steps If Voltaren Gel Fails

If Voltaren gel isn't enough, don't give up. There are several evidence-based options.

---

1. Reassess the Diagnosis

The first step is confirming the cause of your joint pain.

A doctor may recommend:

• Physical examination
• X-rays
• Ultrasound
• Blood tests (to rule out inflammatory arthritis)

Correct diagnosis is critical. Treating rheumatoid arthritis like osteoarthritis won't work.

---

2. Add or Switch to Oral NSAIDs (If Safe)

Oral NSAIDs such as:

• Ibuprofen
• Naproxen
• Prescription diclofenac

may provide stronger relief.

However, they carry risks including:

• Stomach ulcers
• Kidney strain
• Increased cardiovascular risk

These medications should be used under medical supervision, especially if you have heart, kidney, or stomach issues.

---

3. Physical Therapy

This is one of the most effective — and underused — treatments.

Physical therapy can:

• Strengthen muscles around the joint
• Improve flexibility
• Reduce stiffness
• Improve balance
• Decrease long-term pain

Stronger muscles reduce stress on the joint. For knee arthritis in particular, quadriceps strengthening has strong evidence supporting it.

---

4. Weight Management

Even modest weight loss can significantly reduce joint stress.

For knee osteoarthritis:

• Every pound lost reduces knee joint load by roughly four pounds during walking

You don't need extreme dieting. Gradual, sustainable weight changes can meaningfully reduce pain.

---

5. Injections

If topical and oral medications fail, doctors may consider:

Corticosteroid injections

• Reduce inflammation quickly
• Can provide temporary relief (weeks to months)
• Not a long-term cure

Hyaluronic acid injections

• Aim to improve joint lubrication
• Mixed evidence, but some patients benefit

Platelet-rich plasma (PRP)

• Emerging therapy
• Evidence still evolving

A joint injection is usually appropriate when pain significantly limits daily activities.

---

6. Evaluate for Inflammatory Arthritis

If symptoms include:

• Morning stiffness lasting over 30–60 minutes
• Symmetrical joint pain
• Swelling in multiple joints
• Fatigue
• Warmth and redness

You may need referral to a rheumatologist.

Inflammatory arthritis is treated with disease-modifying medications — not just pain relievers. Early treatment prevents joint damage.

---

7. Consider Advanced Imaging

If pain persists despite appropriate therapy, your doctor may order:

• MRI
• Ultrasound

This helps identify:

• Meniscus tears
• Tendon damage
• Bone marrow edema
• Stress fractures

Topical NSAIDs will not fix structural damage.

---

8. Surgical Evaluation (When Appropriate)

Surgery is not the first step — but in severe arthritis, it may become necessary.

Options include:

• Arthroscopy (limited cases)
• Partial joint replacement
• Total joint replacement

Joint replacement surgery has high success rates for severe osteoarthritis when conservative treatments fail.

---

When Joint Pain Could Be Serious

Most joint pain is not life-threatening. However, seek urgent medical attention if you experience:

• Sudden severe joint pain
• Fever with joint swelling
• A red, hot, rapidly worsening joint
• Inability to bear weight
• Significant swelling after injury

These could indicate infection, fracture, or acute gout — conditions requiring prompt care.

Practical Tips While You Seek Next Steps

While waiting to see a doctor, you can:

• Continue using Voltaren gel as directed
• Use heat for stiffness
• Use ice for swelling
• Stay active but avoid high-impact activity
• Try low-impact exercises (swimming, cycling, walking)
• Avoid prolonged bed rest

Movement, when done safely, is usually better than complete rest.

The Bottom Line

Voltaren gel works well for many people with mild to moderate osteoarthritis — especially in superficial joints like the hands and knees. But if your joints still ache, it doesn't mean you're out of options.

Common reasons it fails include:

• Wrong diagnosis
• Deeper joint involvement
• Inflammatory arthritis
• Progressed disease
• Improper use

The solution is not to simply "push through" the pain. It's to reassess and escalate care appropriately.

If you're experiencing joint warmth or heat along with your pain, take a few minutes to try a free AI symptom checker for warm joints — it can help you understand what might be going on before your doctor's appointment.

Most importantly, speak to a doctor if your pain is severe, worsening, persistent, or accompanied by fever, redness, or significant swelling. Some joint conditions can cause permanent damage if left untreated — and rare cases can be serious.

You deserve relief — and there are medically approved paths forward beyond Voltaren gel.
