The shoulder consists of several joints that combine with tendons and muscles to allow a wide range of motion in the arm — from combing your hair your back to scratching your back.
Increased mobility has its price though, It may lead to increasing problems with instability or impingement of the soft tissue or bony structures in your shoulder, resulting in pain. You may feel pain only when you move your shoulder, or all of the time. The pain may be temporary or it may continue and require medical diagnosis and treatment.
The shoulder joint is made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle).
The head of your upper arm bone fits into a rounded socket in your shoulder blade. This socket is called the glenoid. A combination of muscles and tendons keeps your arm bone centered in your shoulder socket. These tissues are called the rotator cuff. They cover the head of your upper arm bone and attach it to your shoulder blade.
Most shoulder problems fall into four major categories:
Tendon inflammation (bursitis or tendinitis) or tendon tear
Fracture (broken bone)
Your elbow’s a joint formed where three bones come together - your upper arm bone, called the humerus, the ulna and the radius,
Each bone has cartilage on the end, which helps them slide against each other and absorb shocks.
They are lashed into place with tough tissues called ligaments, and your tendons connect your bones to muscles to allow you to move your arm in different ways.
If anything happens to any of these parts, not to mention the nerves and blood vessels around them, it can cause you pain.
Here are some of the different ways your elbow can hurt:
One-time Injuries: Some injuries, hopefully, are one-off events, like when you fall or get hit hard while playing a sport.
Dislocated elbow: When one of the bones that forms the elbow gets knocked out of place, you have a dislocated elbow. One of the more common causes is when you put your hand out to catch yourself during a fall. It can also happen to toddlers when you swing them by their forearms - that’s called nursemaid’s elbow. If you think you or your child has a dislocated elbow, call your doctor right away.
Fractured elbow: If one of your arm bones breaks at the elbow, you have a fracture. Usually, this happens with a sudden blow, as you might get in a contact sport or a car accident. And don’t be fooled if you can still move your elbow afterward. If you’re in pain and it doesn’t look right, it could be broken. You'll need medical attention.
Strains and sprains: File these under, “Oof, I think I pushed it a little too far.” When muscles get stretched or torn, it’s called a strain. When it’s ligaments, it’s a sprain.
