Both Stephen Jackson and Corey Maggette are frustrated with their injuries and are even more frustrated that they do not know what is wrong, the San Francisco Chronicle is reporting.

Asked about a latest course of action on his swollen left hand, Jackson said, "I don't know. Ask (athletic trainer Tom Abdenour). I don't know what's going on. I'm not the doctor. I don't think he knows either. ... I'm on my own. I'm just on my own."

Maggette also was stumped about his continuing hamstring problems, which haven't abated despite a variety of treatments.

"It's frustrating - I just don't know what's wrong with it," Maggette said.
