I know it seems silly or like it wont help but really eat the bananas it WILL help
Get Ur potassium checked...I had real bad charlie horses in my legs and then found out my potassium was almost critically low...you might have to take a potassium supplement...bananas help too!
Like she said drink LOTS of water and try eating a banana
Drink plenty of water and rest with your feet elevated.....but your swelling already I.would say talk to your doctor...and Tylonel is safe to take while pregnant so that should help with the leg pain
