Stay active if you have low-back pain
If you have low-back pain, stay as active as you can.
Until about a decade ago, doctors often advised people with back pain to rest in bed or "take it easy". A recent review by the Cochrane Collaboration confirmed that bed rest can be counter-productive, while staying as physically active as you can helps reduce pain and improve mobility. The evidence is not clear that staying active helps people with sciatica, though it's reasonable to think that they too are likely to fenefit, the researchers said. Physical movemeent may help speed recovery by increasing blood supply and nutrients to soft tissues in the back.
