Cindy McCain sustains minor hand sprain

WEST BLOOMFIELD, Mich. (AP) - Republican John McCain's wife has been treated for a "minor sprain" after someone at a campaign event in Michigan shook her hand firmly.

A campaign spokeswoman says Cindy McCain left the West  Bloomfield, Mich., campaign event Wednesday for X-rays at a local hospital after an enthusiastic supporter squeezed too much.

McCain's wife has had previous surgeries for carpal tunnel syndrome and the handshake exacerbated the condition.

Spokeswoman Jill Hazelbaker says Mrs. McCain will campaign as planned on Thursday.
