Mine was just feet and hands mostly during the night at the very end with my last pregnancy. My hands would feel much better when I would wash them in really cold water (or just hold them in the water) as soon as I woke up in the morning. Definitely mention to your doctor, especially if you're not just experiencing the swelling.
It could be normal but if combined with facial swelling, high blood pressure, and/or protein in the urine it could be preeclampsia. Always talk to your doctor.
