How Is Impingement Syndrome Different From Shoulder Bursitis And Rotator Cuff Tendinitis?

Impingement syndrome – the top bone in your shoulder is rough on the bottom and is scratching and irritating/pinching the tissue underneath.
shoulder bursitis – the bursa sacs are inflamed.
rotator cuff tendinitis – this is inflammation in one of the tendons in your shoulder. You can also get a tear in one of these tendons – that really hurts.
