Is it normal for my daughter's fractured arm to still be painful 2 weeks after plaster came off?

Not usually.: If your daughter broke her arm and was treated with a cast, usually the arm is not painful when the cast is removed. Casts are usually left on for about 5 weeks. If she did not have the cast on for 5 weeks, she might still be painful. I would recommend returning to the physician who removed the cast as she may need to have the cast put back on.
