Numbness is the inability to feel anything when your skin is touched.
It may feel like the part you touch does not belong to you. Tingling
(paresthesia) is a pins-and-needles sensation, like when your hand falls
asleep. If you bump your "funny bone," you may feel intense pain
with numbness and tingling shooting down your arm. This feeling is not serious,
lasts only briefly, and will go away on its own.
Numbness and tingling may mean that
nerves have been injured or pinched, swelling is
putting pressure on nerves, or blood vessels have been injured. This can occur
gradually from an overuse injury or from a sudden (acute) injury, such as a
fracture, dislocation, or severe sprain. It is normal to have temporary changes
in feeling after an injury or when you have swelling. Home treatment may help
relieve swelling that can cause numbness or tingling.
Snapping hip syndrome, sometimes called dancer's hip, is a condition in which you hear a snapping sound or feel a snapping sensation in your hip when you walk, run, get up from a chair, or swing your leg around. For most people, the condition is little more than an annoyance and the only symptom is the snapping sound or sensation itself. But for dancers or athletes, snapping hip syndrome symptoms may also include pain and weakness that interfere with performance.
