Inflammation of the biceps tendon’s long head. The tendon becomes inflamed and swollen in the early stages. The tendon sheath (covering) can thicken as tendinitis progresses. The tendon itself frequently thickens or expands.
Because of the inflammation, the tendon is often dark red in the late stages. Damage to the tendon can occasionally result in a partial or complete tear.
WHAT ARE THE SYMPTOMS?
Pain or tenderness in the front of the shoulder that may move down the upper arm bone.
An occasional snapping sound or sensation in the shoulder.
WHAT ARE THE CAUSES & RISK FACTORS?
In most cases, biceps tendon damage is caused by a lifetime of normal activities. Everyday wear and tear causes our tendons to weaken over time. Overuse — repeatedly performing the same shoulder motions — can aggravate this degeneration.
Many jobs and routine chores can result in overuse injury. Sports such as swimming, tennis, and baseball, which require repetitive overhead motion, can also put people at risk for biceps tendinitis.
Other shoulder problems associated with biceps tendinitis may be exacerbated by repetitive overhead motion. Overuse is frequently the cause of rotator cuff tears, osteoarthritis, and chronic shoulder instability.
