If this question was asked about 70 years ago, then the answer would have been yes. Yes you have pain, yes you should stay in bed and “rest”. However, with the emergence of modern day medicine and evidence based science, researchers and practitioners found that bed rest is actually not very effective in helping you manage your pain, in fact – it may even delay your recovery. 


Staying in bed for any prolonged period can make you stiff and increase pain. When you don’t move and bend, you lose muscle strength and flexibility. With bed rest, you lose about 1 percent of your muscle strength each day. And you can lose 20 to 30 percent in a week. It becomes more difficult to return to any activity. As you become weaker and stiffer your recovery takes longer.


The sooner you start moving, even a little bit, or return to activities such as walking, the faster you are likely to improve.
