I only had it for a few weeks-just over a month at a time, but it it truly awful! I feel so bad that you're dealing with this. I tried so many things-but what really helped was yoga. Just gentle yoga at home. Especially the inversion poses like downward dog, propping my feet up over my head, the twist poses, bridge pose. I don't remember what else, but anything that felt good, I did it. If it didn't, I stopped
I still do yoga now, and notice if I don't do it at least weekly, my back starts flaring up! It's a reminder because in a day to day basis, I don't consider myself to have a bad back thankfully (but I apparently do)
Yoga so I can lift! It's a good trade
