Cooling relieves pain & swelling
Whether in the knee, shoulder, elbow or foot – bursitis can affect many joints and is almost always very painful. It’s often caused by overuse, pressure, small injuries or inflammatory conditions like arthritis or gout. Infections can also trigger it.
Typical symptoms: swelling, redness, warmth and limited mobility. Pain often worsens with movement and may be acute or chronic.
A proper medical diagnosis is essential to rule out other causes. In most cases, conservative treatment helps: rest, elevation and, if necessary, anti-inflammatory medication. In severe cases, drainage, cortisone or antibiotics may be needed.
Cold therapy has proven especially effective:
It reduces pain, inflammation and swelling. That’s where Kalter Bruder® comes in – with long-lasting cooling and fast relief for bursitis.

4. Cold therapy
Targeted cooling can effectively help relieve pain and combat inflammation in the affected joint during bursitis. Cold therapy slows down the inflammatory process and reduces the activity of pain receptors, providing rapid relief from discomfort.
A consistent, gentle cooling effect penetrates deep into the tissue, reaching inflamed structures while preventing the so-called “reactive hyperemia”—a counter-reaction in which the body increases blood flow to compensate for excessive cold, potentially weakening the intended effect.
However, the benefits of cold therapy are only achieved when cooling is long-lasting and evenly applied. Superficial or overly cold applications, such as ice packs, may offer temporary pain relief but often fail to reach the deeper areas where cooling is most needed.
THE NATURAL POWER OF KALTER BRUDER®
This is exactly where our KALTER BRUDER® Relax gel comes in, because we have specially tailored our recipe to a long-lasting cooling effect. The fresh gel from the aloe vera plant and arnica in particular are known for their anti-inflammatory and soothing properties. Ingredients such as menthol and camphor also have a cooling effect and can help to relieve pain and swelling.
KALTER BRUDER® offers a practical and efficient way to use the positive effects of cold therapy specifically for a bursitis. Thanks to its cooling effect, the gel provides gentle and constant deep cooling without damaging the skin or restricting mobility.
