Does Heat Help With Tendonitis and When to Use It

Tendonitis, an irritation or inflammation of a tendon, causes discomfort and limits movement. Understanding the appropriate use of heat and cold therapy is important for managing symptoms effectively.

What is Tendonitis?

Tendons are tough, fibrous cords of connective tissue that link muscles to bones. They enable movement by transmitting muscle force to the skeletal system. When these tendons become irritated or inflamed, the condition is known as tendonitis.

Tendonitis typically results from repetitive motions, overuse, or sustained stress on a tendon. It can manifest as pain, often a dull ache, particularly when moving the affected limb or joint. Other common symptoms include tenderness, swelling, and stiffness. This condition frequently affects areas such as the shoulders, elbows, wrists, knees, and heels.

Applying Heat for Tendonitis

Heat therapy can be beneficial for tendonitis, particularly once initial inflammation has lessened. It works by increasing blood flow to the affected area, delivering oxygen and nutrients to support healing. This increased circulation can also help relax tight muscles, reducing stiffness and easing pain. Heat can also prepare tissues for stretching or rehabilitative exercises by improving flexibility.

Heat is most suitable for chronic tendon pain, stiffness, or before physical activity. Common methods include heating pads, warm compresses, warm baths, or heat wraps. For moist heat, a damp cloth can be used with the heat source.

Apply heat for 15 to 20 minutes, two or three times daily. Avoid applying heat to acute injuries or areas with swelling, as it can worsen inflammation. Always use a barrier, like a towel, between the heat source and skin to prevent burns. Ensure the temperature is warm, not excessively hot.

Applying Cold for Tendonitis

Cold therapy, also known as cryotherapy, is effective for managing acute tendonitis symptoms. It functions by constricting blood vessels, which helps reduce blood flow, decreasing swelling and inflammation. Cold also acts as a numbing agent, dulling pain signals and providing temporary relief.

Cold therapy is most useful for sudden injuries, immediate pain, or to reduce swelling after activity. It is recommended during the initial 24 to 72 hours following an injury. Common application methods include ice packs, cold compresses, or a bag of frozen vegetables wrapped in a cloth. Ice massage can also be used for localized pain.

Apply cold for 15 to 20 minutes, every four to six hours. Always place a towel or cloth between the cold source and skin to prevent frostbite or skin damage. Allow skin to return to normal temperature before reapplying cold.

Deciding Between Heat and Cold

The choice between heat and cold therapy for tendonitis depends on the injury stage and primary symptoms. For new, acute injuries characterized by sudden pain, swelling, or redness, cold therapy is generally preferred. Cold helps minimize inflammation and numb the area, controlling the immediate effects of the injury.

Conversely, heat therapy is more suitable for chronic tendon pain, persistent stiffness, or dull aches after the initial inflammatory phase has passed. Heat promotes muscle relaxation and increases blood flow, which can aid in long-term healing and flexibility. Using heat too early on an acute injury can worsen swelling.

Alternating between heat and cold, known as contrast therapy, may be beneficial, particularly for exercise-induced pain or chronic issues. This approach can help stimulate blood flow and reduce soreness. If pain or swelling persists or worsens despite self-care measures, consulting a healthcare professional is advisable for proper diagnosis and treatment.
