What would cause balls of feet and palms of hands to itch and cause upper flank pain?

Allergic reaction. Palmar and plantar itching (palms and soles) usually signifies an allergic reaction, but flank pain generally means a kidney problem like an infection or stone. It's unusual to have both together. Either one could signal a serious problem, though, so it's important to see a doctor and get all this sorted out soon.
