In response to the enquiry: “My hand feels swollen after a long flight, should I worry?”
Hands and fingers swell and uric acid accumulates in the joints when the humidity is high. This is very painful to anyone with arthritis and gout.
Numbness in the arm and the hand occurs often when the arm and the hand remain motionless for a long period of time.
Edema in the ankles, the legs, the knees, the joints, and the hands occurs with infrequent urination as on a long haul flight.
