Fox News reports that as people age, their bodies tend to take on new quirks and ailments that can sometimes be painful.

Those experiencing shoulder pain could have a condition called "frozen shoulder," which mostly occurs in middle age.

Frozen shoulder is an inflammatory condition that creates scar tissue around the shoulder joint capsule, causing pain, according to Samantha Stuek, MD, sports medicine physician at HSS. 

"This significant increase in pain comes seemingly out of the blue, more at night," Dr. Stuek said.

"And all of a sudden, this progressive decrease in range of motion [gets] to the point where people are coming in saying they can't lift their arm, they're having trouble putting their jacket on, they can't wash their hair and are having pain with any of those motions," explained Dr. Stuek. 

The average age of onset for frozen shoulder is 55, and the condition is about four times more common in women, according to Dr. Stuek.
