I have some minor back pain, I don't sleep on a soft mattress, and has reduced the pain and probably help straigten it. If that doesn't help see an acupunture practitioner, as Acupuncture can help to reduce the chronic pain, and it becomes more effective as it goes on.
Its currently funded by the NHS cause its a cheaper alternaltive to painkillers. And the effects are more lasting.
Can't say I know what that feels like because I have no issues what so ever. However just remember there are plenty of things you can do in this world that don't require back strain or serious physical activity. Lots of really fun things if you get creative I'm sure you can discover a hidden talent that's just as fun that you didn't know you could do before. (and those past hobbies are probably the cause of your condition so maybe it's a sign not to do them).
Most people with chronic conditions do. It's hard to explain to people that i'm not lazy, i'm exhausted by even the smallest of tasks sometimes. My body doesn't absorb vitamin B12 (which deals with your energy levels) normally, so I have to have injections. On top of that, I have hypothyroidism and the shame of the swelling in my neck and the weight gain is something i've had to deal with my entire life.
There are ways to deal. Finding a good doctor who will listen to your concerns is one. Understanding the risks and benefits of different medications and exercises is another. The important thing is to never allow yourself to get stuck in that trapped feeling. You may feel trapped, but there are any number of ways to escape if you're patient.
Also, this occasionally makes me feel better: [link]
