Such terrible pain

Husband and I went to ER last night since I was in such cruciating pain with my back and I felt like I was having a hard time breathing. After hours and hours of waiting until I got to talk to a Dr about it we find out it's gull bladder attacks being cause by gull stones. I was crying so bad with not only the pain but because there's nothing that will make it stop I feel helpless. I'm 29 wks & 3 days and there's no pain medicine besides Tylenol that I could take. & I can continue to have these bad attacks and just have to deal I'm so overwhelmed. Has anyone else had this come of anything and got worse being pregnant? I've never had this issue before mine and haven't had a single surgery either. If anyone has any suggestions please let me know thank you❤️
