Transcutaneous electrical nerve stimulation
(TENS) – a technique that uses a small electronic device to direct
mild electric pulses to nerve endings that lie beneath the skin in a painful
area. TENS may relieve some arthritis pain. It seems to work by blocking pain
messages to the brain and by modifying pain perception.
X ray – a procedure in which low-level
radiation is passed through the body to produce a picture called a radiograph.

loss, bone damage, and bone spurs.
