rotator cuff disorder causes pain and weakness in
your shoulder. It may be uncomfortable or impossible to do everyday activities,
such as combing your hair, tucking in your shirt, or reaching above your head.
Most often, you will feel the pain on the side and front of your upper arm and
shoulder. You may have pain during the night and have trouble sleeping on
that side. Pain is almost
always worse when you make overhead movements.
Because of the pain, you may try not to use your arm. And that can cause even more
weakness and stiffness in the shoulder.
The amount of pain usually depends on how much damage there is:
Minor damage. Pain most often occurs only when you
are active and is usually relieved with rest.
Moderate damage. You will likely notice pain both
during and after activity. Pain may also occur at night, especially when you
lie on your shoulder.
Severe damage. You may have continuous pain.
Sometimes the pain isn't directly related to the amount of damage. For
example, your rotator cuff may have minor damage, but strength and the loss of
range of motion may be severe because it's too painful to move in certain
ways. This is especially true if you normally make a lot of overhead movements.
Symptoms of rotator cuff tendinitis
In tendinitis (inflammation in the tendon), the pain usually starts gradually, over the side of the shoulder and the upper
Your shoulder and arm aren't particularly weak but it hurts to use them.
The pain may spread down the outside of the upper arm,
even to the elbow.
The pain may be worse at night and may keep you awake, especially if you lie on that side.
Lifting the arm to the side
or to the front makes the pain worse.
Over time, the pain may get worse or you may have
constant pain. In some cases, this is because you actually have one or more
small tendon tears.
Some people also have tendinitis in other parts of the shoulder. And some people have neck pain from using other
muscles to help move the shoulder.
