i have been having alot of pain in my pelvis and back area i'm 26 weeks pregnant and when i walk it feels like my bones are grinding together i can actually hear them clicking and stuff. i have read up that there isn't a lot that can be done, i cannot take codine as am allergic so all i can have is paracetemol which does nothing for me. i have a bump support but this makes the pain worse, any one else have this with any good ideas what i can do?
