I am 20 weeks pregnant and have been experiencing some lower back throughout the pregnancy. This is my second pregnancy. However over the past few days I have been getting severe pain in lower left back and hip and through my left leg. The pain intensifies at night and last night I was kept awake with the severity of the pain and tonight its starting to get the same with it starting in my back travelling down through my leg. I had something like this my last pregnancy but not as painful and not until I was over 34 weeks. Shall I contact a midwife or is there not much can be done I am in a lot of pain.
