Please help, Is this normal at 34 weeks pregnant?

Ok, so here goes, Im 34 weeks pregnant and been getting excruciating pain in my pelvis, Basically where the babies head is. Ive recently been up to the hospital about this pain about a week ago now, It basically hurts ever movement i make doesnt matter wat movement it is it hurts, But when im sittin down being completely still it doesnt hurt. Now the midwife said its just my pelvis trying to relax and stuff and everything was fine when i went up. But the pains nearly unbareable! What do use think it is? Is there anything i can do? Or basically i just have to suck it up and get over it lol?? I have a 14 mnth old son so i cant really relax too much!
