I had that too. Drink more water and elevate your feet. Also, my midwife said to avoid crossing my legs and exercise more, something lite, such as walking.
taking calcium magnesium will help plus drinking lots of water, elevating your legs andi ice sometimes.
For your hands dip them in cold water with a little ice this helps me alot. I haven't been able to wear my wedding rings in about a month especially with all this heat we've been experiencing
