What Causes Bicep Pain?

The bicep muscle is one of the most important for your upper body strength. An injury to this hardworking muscle can make day-to-day tasks difficult.

There are two places where the bicep muscle connects: the shoulder and the elbow. In your shoulder, tendons connect your bicep into the shoulder joint. In your elbow, tendons keep the muscle attached to your lower arm.

We most often see bicep injuries at the connection point with your shoulder. Strains or tears can develop in the ligaments. The tendons can also slip out of the groove at the top of the humerus — the bone of the upper arm — that holds the muscle in place. We sometimes see injuries to the bicep tendons at the elbow, but these are more rare.

These conditions result in bicep tendonitis, which is a strain or tear in the tendons that can cause a great deal of pain.

You may envision a bicep injury resulting from a single incident, like lifting a particularly heavy dumbbell or struggling with heavy furniture. But most of the time, bicep injuries in adults are overuse injuries and they are more common as we age. They could result from repeated lifting required for your job, picking up young children or even playing your weekly round of golf.

Since these kinds of injuries usually develop slowly over time, they are hard to prevent. Be sure to listen to your body when an activity is causing pain that goes beyond temporary muscle soreness.
