The distal biceps muscle is located in the front of your arm (see image above). This muscle helps you to bend your elbow and twist your forearm. Unfortunately, the biceps is prone to injury, especially the biceps tendon, which connects the bicep muscle to the radius bone in your forearm. This tendon can weaken over time, which is called tendonosis. If you have tendonosis of the biceps tendon, you may feel a dull or sharp pain just past the elbow in the forearm. There’s also a chance that you will feel no pain.
Tendonosis can sometimes lead to a tear or rupture in the tendon. Tears or ruptures can happen when you are lifting something heavy such as furniture or weights.
Some signs that you may have torn or ruptured your biceps tendon include:
- A popping feeling at the time of the rupture or tear
- Pain in the elbow area
- Warmth in the elbow area
- Muscle spasms
