Good day girls! I don't know what to do anymore, four births, very painful coccyx and in the chest area, it hurts even to walk, I did an ultrasound between the pubic joint bones 11mm, but they write that the symphysis is without peculiarities, the gynecologist says, she doesn't react at all, she says you will give birth yourself and everything, but I am very afraid to remain disabled, can anyone have experienced this?
