Mickelson playing through pain of psoriatic arthritis

Phil Mickelson is beginning his quest for the 2010 PGA championship and he's playing with the pain of  psoriatic arthritis. He revealed his condition on Tuesday.

Mickelson says he experienced his first symptoms of the potentially debilitating disease five days before the U.S. Open began two months ago.

Dr. Christopher Ritchlin, professor of medicine at the University of Rochester Medical Center, says 80 percent of people who get psoriatic arthritis tend to have psoriasis first. He says patients usually have psoriasis for 10 years before also developing arthritis. Patients usually get psoriatic arthritis between the ages of 20 and 50 but children can get it too.
