I’m very sorry to hear that, chronic pain is debilitating, it affects everything you do and if it’s the back it’s one of the worst places.Had a couple of MRI's...got bulging discs. Back has gotten steadily worse over the years as has the burning pain....
Tried umpteen things.
Now, even lying down is painful...
Smoking or vaping Cannabis can make a huge difference, but obv it’s illegal so I can’t recommend it, also I’ve. It taken it so have experience.
There are much stronger pain killers than paracetamol and ibuprofen but most are opioid based and addictive.
Steroids can really lower inflammation but are only suitable for short term use as they have serious side effects
