Hi. I have severe lower back pain which goes to my right leg. I am unable to sit or walk or even change side in bed without pain. The pain started in 4th month of my pregnancy and became worse with time. It was in lower back and pubic area. I was told it's coz of pelvic girdle and will go after delivery. Now my baby is 10 days old but pain is only getting worse. Now the pain is in lower back right buttock and right leg. I am not able to sit for long to feed my baby.
