Get more vitamin D. Vitamin D has been shown to cause chronic back pain in some cases, but getting more of this important vitamin is an easy thing to do. Have some milk and spend time outside to get the most vitamin D you can. Most people are vitamin D deficient and don't know that, so make sure to talk to your doctor about checking your blood to be sure.

Your sitting position can cause back strain if done improperly. If you're sitting at a desk chair for long hours, make sure to sit with your lower back touching the back of the chair and leaning back slightly so that your back muscles can disengage and not get worn out.
