Horrible back pain!😭😭

So, I am currently 29weeks pregnant with my 2nd child and I get sever back pain! It's not like any other type of pain. This pain starts in between my shoulder blades and wraps all the way around to the upper part of my stomach. The pain is so awful that it has made me throw up! I have been to the ER 4 different times and I've seen my doctor for this and they all tell me the same thing.... "the baby is just hitting nerves" NO! They don't understand how BADLY this pain is! It is worse than labor pains I'm not joking! It makes me want to die it hurts so bad and none of this happened with my first pregnancy! The pain will happen once or twice a week and when it does it does not stop for hours and nothing I do helps!! Has anyone else ever had this kind of pain? And was it something other than the baby on nerves? Bc it is really scaring me! I still have 11 weeks til my due date and if this pain continues idk how I'm gunna make it 11 more weeks! 😭😭
