Conditions

Usually muscles and joints. Pain into the arm or numbness needs a look.

The capsule tightens, so the shoulder moves less. It runs over months.

A torn shoulder tendon: pain outside, pain at night, hard to lift.

Tendons, capsule or joint. The movements that hurt narrow it down.

A cruciate ligament torn on a twist. The knee swells fast and gives way.

The cartilage lining the knee thins: pain, stiffness, harder walking.

Many causes. Where and when it hurts points to which one.

A tear at the meniscus anchor, so it no longer spreads load.

A torn pad of cartilage: pain, catching, or a knee that locks.

Pain around the kneecap, worse on stairs and after sitting bent.

Very common, and most settles — but some warning signs need a doctor.

A disc presses on a nerve: pain, numbness or weakness down its path.

Pain from the back or buttock down the leg, from a nerve under pressure.

From the joint, the tendons or the muscles. Where it hurts is the clue.

A click or clunk in the hip when you move the leg, and what causes it.

A compressed nerve at the wrist, numbing the fingers at night.

A finger tendon catches in its sheath, so the finger sticks or locks.

Pain on the outer elbow from repeated wrist work. Not only in tennis.

Pain and stiffness behind the ankle from repeated load.

Twisted ligaments. Surgery is rare; rehabilitation stops it recurring.

Heel pain from the sole, worst on the first steps of the morning.

Bone thin enough to break in a light fall, with no symptoms until it does.
