Hi, I'm Dr. Pecoraro. This is a model of the spine. These are the bones, the nerves, and the arteries. A slight twist of these bones can cause pressure on the nerves and pain in many parts of your body. A chiropractor can realign your spine and help give you relief from pain. The exam is only $10. Call 1-800-464-BACK. It's safe to find out. Offices in Staten Island, Brooklyn, Queens, and Manhattan. Call 1-800-464-BACK.
