Can all 5 fingers be affected by carpal tunnel?

Yes, all five fingers can be affected by carpal tunnel syndrome, although the most commonly impacted areas are the thumb, index, middle, and part of the ring finger. This condition occurs when the median nerve, which runs through the carpal tunnel in the wrist, becomes compressed. Symptoms may include pain, numbness, or tingling in these fingers, but the little finger is typically not affected since it is innervated by a different nerve.
