Hydronephrosis 😩

The day after my 23 week apt I started getting really bad pain in my back. It got to a point where I couldn't stand, sit, lay, etc. I could barely breathe it hurt so bad! I went to the ER where they couldn't tell me anything other than I wasn't in labor and the baby was fine. Well after 4 apts and lots of waiting they told me I have swollen kidneys and that there's not really anything they can do about it unless I want surgery to put a stent in that goes from my kidney to my bladder until the end of my pregnancy. The Dr seemed really against this since stents cause so many more unsavory symptoms. I obviously don't want surgery and didn't think the stent sounded worth it and luckily the pain has subsided for the most part. I'm 31 weeks now and the pain comes back randomly. It sucks! And I can't take anything for it!!!
Anyone had this problem? 
I'm just complaining here and am sympathetic to anyone having issues 😊
The worst part is that my "morning sickness" (all day sickness 😏) lasted until 22 weeks. I was finally feeling better and then, bam! Kidney pain.
