This is my fourth baby and never have I had this back pain before. I'm 34 wks. My husband rubs my back every night but it still kills me by the afternon. My doc said to wear the maternity belt wich helps, but only for a little while. I take warm baths at night to help. My doc just said that it is a normal complaint for someone having their 4th baby. My pelvic bone is killing me. At this point most women could careless about being intimate with their husbands, I however would love to, but with my back and pelvic pain I just can't get into it. Any suggestions would be sooooo appreciated.
