Medical Reports: Back pain

WSVN -- Bud Alvarez had such bad back pain he couldn't stand sitting at his desk all day.

Bud Alvarez: "It was really unbearable. It was terrible."

Nothing he tried relieved the pain. Then, chiropractor Alan Shaff treated him with the Fenzian.

It uses electric impulses to talk to the central nervous system.

Bud Alvarez: "This is sort of like a reset button on a computer."

The device delivers electric currents that replicate healthy nerve impulses. As it's rolled over the back, the device hones in on areas of low electrical resistance, helping with the pain.

Dr. Shaff: "It restores the electrical impulse and the connection of the nervous system throughout the body."

That puts the body on the path to healing.

Dr. Alan Shaff: "Faster recovery, reduction in muscle spasm, reducing in swelling and inflammation. I would say 50 percent faster than I ever saw before."

The device works better on injuries than chronic pain, and it won't repair tissue damage. It's used for herniated disks, pinched nerves, stenosis, sprains and strains.

Bud now goes about his daily routine remembering what it used to feel like.

Bud Alvarez: "I had to lean forward the whole time I was driving just like this, and this is the way I would drive the whole time just so my back wasn't touching anything."

Skeptical at first, it only took a few treatments with the device to change his mind.

Bud Alvarez: "I haven't had pain there at all since. It's never come back."

And he hopes it never does.

Shaff says, in many cases, insurance will cover the cost of the 20-minute treatments. Without insurance, one treatment costs between $50 and $75.
