If you’ve been dealing with tendonitis, you’ve probably asked yourself, “Should I use heat or ice to feel better?” It’s a common question—and the answer depends on where you are in the healing process. In this article, we’ll answer the question: Does heat help tendonitis? and share practical tips to get the best results from heat therapy.

What is tendonitis?

Tendonitis is the inflammation or irritation of a tendon—the thick fibrous cord that connects muscle to bone. It’s often caused by:

• Repetitive movements (typing, lifting, throwing, etc.)
  
• Overuse or strain during activity
  
• Poor posture or ergonomics
  
• Sudden increase in physical activity
  

Common areas affected by tendonitis include the shoulder (rotator cuff), elbow (tennis elbow), wrist, knee (jumper’s knee), and Achilles tendon.

Symptoms of tendonitis include:

• Pain near a joint
  
• Swelling and tenderness
  
• Stiffness or reduced range of motion
  
• Pain that worsens with movement
  

Does heat help tendonitis?

✅ The short answer: Yes—but only in certain cases.

Heat therapy can help relieve tendonitis, but it’s most effective after the initial inflammation has gone down. That’s because heat increases blood flow, relaxes tight muscles, and reduces stiffness—all of which are helpful during the chronic or healing phase of tendonitis.

When to use heat vs ice for tendonitis

Phase of Tendonitis	Symptoms	Best Therapy
Acute phase (first 48–72 hours)	Swelling, sharp pain, redness	❄️ Ice
Subacute/Chronic phase (after 3+ days)	Stiffness, tightness, dull ache	🔥 Heat

❄️ Use cold therapy (ice):

• Immediately after injury or flare-up
  
• To reduce swelling and inflammation
  
• Apply ice for 15–20 minutes, 2–3 times a day
  

🔥 Use heat therapy:

• Once swelling has gone down
  
• For muscle tightness or stiffness around the tendon
  
• Before stretching or physical therapy to warm up tissues
  
• Apply heat for 15–20 minutes, using a warm towel, heating pad, or hot water bottle
  

Benefits of heat for tendonitis

1. Relaxes muscles surrounding the inflamed tendon
   
2. Increases circulation, bringing oxygen and nutrients to speed up healing
   
3. Reduces stiffness, improving flexibility
   
4. Eases pain, especially with movement after rest
   
5. Prepares tissue for stretching and rehabilitation exercises
   

Best ways to apply heat

Here are safe and effective ways to use heat therapy for tendonitis:

1. Moist heating pad

• Penetrates deeper than dry heat
  
• Ideal for shoulders, knees, and elbows
  

2. Warm compress or towel

• Easy to make at home with hot water
  
• Wrap in a thin towel and apply directly to the area
  

3. Warm bath or shower

• Relaxes the entire body
  
• Perfect before stretching or rehab exercises
  

4. Heated gel packs or heat wraps

• Portable and reusable
  
• Useful for wrists, forearms, and ankles
  

📌 Tip: Never apply heat directly to the skin—always use a barrier to prevent burns.

Heat therapy safety tips

✅ Use heat for 15–20 minutes at a time
✅ Wait at least an hour between applications
✅ Avoid using heat on a fresh injury or if swelling is present
✅ Don’t fall asleep with a heating pad on
✅ If you have diabetes, poor circulation, or neuropathy, consult a healthcare professional before using heat

Complementary treatments for tendonitis

In addition to heat therapy, consider these treatments for faster recovery:

• Physical therapy to strengthen and stretch the affected area
  
• Massage therapy for tight muscles
  
• Anti-inflammatory medications (e.g. ibuprofen)
  
• Activity modification to avoid aggravating movements
  
• Ergonomic adjustments if the tendonitis is work-related
  
• Cortisone injections (in severe cases, prescribed by a doctor)
  
• Gradual return to activity once pain has improved
  

When to see a healthcare provider

Heat therapy is great for mild or moderate tendonitis, but see a doctor or physiotherapist if:

• Pain lasts longer than 2–3 weeks
  
• You experience weakness or limited mobility
  
• Symptoms get worse despite self-care
  
• Tendonitis interferes with work, sleep, or daily activities
  

Final thoughts

So, does heat help tendonitis? Yes—if used at the right time. Once the initial inflammation subsides, heat therapy can ease stiffness, improve flexibility, and support your recovery journey. When combined with stretching, strengthening, and rest, heat can be a valuable tool in managing and healing tendonitis.
