Swollen and numbness in hands

Hi Mummies, Every day after wake up will experience swollen hands and when I clench my fist it feels sore and numb. I try to sleep on my side at night and I notice that if I lie on right side left hand becomes swollen, if lie on left side right hand becomes swollen. Is it normal or sign of pre-e? Currently @35 weeks Update: doctor said it's normal and due to water retention
