Hi all, in new here, I'm 37 and have nerve damage in my lower back caused from a gymnastics accident 20 years ago. Most the time my back pain is manageable but just recently I've had a terrible bout of muscle spasms in my back causing me to be off work as the pain was totally unmanageable at work. I'm quite active generally walking my dog but wondering should I do more, specifically wondering about running or is that too much stress on my back? I want to try and manage my issues and strengthen my back. Can anyone offer any advice?
