Hi, I have a similar history of lower back pain and have recently had 2 major knee operations for injuries. So I’ve been on a lot of pain meds over the last 6 months and just had a facet joint block L4/L5. So I can relate and sympathise with your pain. I’m not so familiar with your meds as I’m in the Southern Hemisphere and we have slightly different names here. But what I’ve found that seems to work for my lower back pain is a combination of paracetamol and a muscle relaxant.( Besides the heat/cold etc). Both are non addictive and ok for the tummy. But discuss with your dr first. I may take something with it to protect my stomach, if I’m worried. (here it’s called nectizole/nexium/altosec). I also try and not overdo things, which is easier said than done and I use breathing meditations for pain relief. There are some wonderful apps that you can download. Try Insight Timer. Has such a huge variety of meditations for different ailments. I’ve also been doing hydrotherapy for my knee rehab. The water is nice for my back too, but you have to be careful not to overdo it. The water is deceptive. I believe that the the bottom line is self kindness and self love and listening to your body. Again easier said than done...when you are in agony. Good luck.
