Lower back PAIN!!!

Any of you Nov mamas experiencing intense lower back pain?! What has/is helping you? This whole entire pregnancy I’ve been lucky with few ailments and trying to keep my complaining to a minimum because I’m so excited to meet her and it’s all for a happy ending ... but holy HELLO. Since Saturday I’ve been in so much pain. Especially on my right lower back. Today at work I felt like throwing up and crying at my desk that’s how bad it was. Luckily I also had my 36 week appointment scheduled for today and doc stated my cervix is closed and thick, so no signs of labor. Someone tell me it won’t be 4 weeks of this?! Nothing has helped. I’ve taken Tylenol, bounced and stretched on the ball, legs up in the air, bath.. I drive with the heated seats to and from work in 80 degree weather for relief 😔 please send me your suggestions and recommendations. TY!!!
