Hello everyone. Girls, I have a question. 23 weeks pregnant, strong pains in the lower back and slightly below it started. It gets so bad that I can't even stand up! It feels like my whole spine has turned to stone. I wrote to my gynecologist, she said it's ok, that it's just a load on the spine, but not to this extent? I do exercises for pregnant women, wear a bandage, nothing helps. Maybe someone had something like this?
