The neck and shoulders are complex and interconnected areas, and medical problems that affect one often affect the other, as well. Pain and dysfunction from injuries or conditions that impact the joints, muscles, and other structures can easily spread from the neck to the shoulder(s) and from the shoulder(s) to the neck.
While dead hangs may be OK for people with good upper-body strength and no shoulder problems, they can be risky for others. People with shoulder hypermobility (excessive motion of the shoulder) or shoulder instability (such as those who easily dislocate their shoulder) may need to be cautious. The shoulder, by design, is a relatively unstable joint. It has a large ball-type bone called a humerus, which sits in a relatively small socket called a glenoid.
The elbow is an underappreciated joint that brings many daily tasks within your reach.
Ridges in fingernails can run horizontally or vertically.1 They are common and harmless, but some fingernail ridges—particularly horizontal ones—can indicate a health problem such as a thyroid issue.
Arm pain can be in the upper or lower arm. You may feel arm pain on the outside of your shoulder. Arm pain can also travel further down the arm toward the elbow.
