Hi there I m currently 30 weeks pregnant and suffering with awful sciatica on my left side, my buttock cheek keeps bruising, is this normal? Also I keep getting an awful sensation in my legs especially at night when trying to sleep, it isn t painful but very irritating it makes me feel the need to move them constantly and getting comfortable with it seems impossible, it feels like a creeping feeling in my legs, my arms have started doing the same too just recently, any advice would be greatly appreciated, kind regards Charlotte Roberts
