Why Am I hurting this bad!!!???

Ok so I am 35 weeks and 2 days and this is my second pregnacy and for the past month I have been hurting in my lower back into my hips and down into my legs. Now my doctor told me that to hurt was normal because the baby is growing and dropping but I didn't hurt like this with my first one which was a boy. I mean yes I was a little uncomfortable but it's nothing like this. I'm having a little girl and she has put me through it all from bad morning sickness to wanting to sleep my life away. But the hurting just started and has progressed to the point where it hurts my back for me to breath and it hurts for me to even walk. And it's like I have restless legs syndrome I can't sit in one position for too long... Im steadly shifting and its interfering with My sleep. I've taken Tylenol and they perscribed medicine for it but I hate having to take all that. Too scared I'll hurt her. My next OB appointment is tomorrow but what do y'all think I should do to help ease the pain without all the medicine? Help Please!! :(
