Back and neck pain can strike at any time - so this advice may help in the short term.  Remember every back or neck condition is individual, and the advice provided here is of a general nature. We cannot accept any responsibility for action taken as a result of your reading this website
First and foremost, DO NOT IGNORE THE PAIN.  It is there for a reason - the body's way of telling you something is wrong.  It may sound obvious, but the first step is to stop doing whatever started the pain attack in the first place.  For example, if you are gardening and feel a sudden sharp twinge, don't be tempted to do "just another five minutes" before it gets dark, or before the rain comes on.  Stop what you are doing and ease yourself gently into a more comfortable position.

Emergency Help

DON'T be a hero.  If it is more comfortable to crawl around on all fours to get to the bathroom than to stand up, then do so.
DON'T do any bending, twisting or lifting.  Resolve to learn the correct techniques.
DON'T say no if a partner or friend offers to massage your back. Just ensure they treat you gently and stop them if anything they are doing causes pain.  Do NOT allow them to touch the spine.
DON'T rush back to the activity which caused the pain, even when you feel much better.  In 100 years who will know or care if the lawn was uncut, kitchen extension built or garden shed tidied out.
Try lying face down on the floor immediately the pain starts, to take the pressure off your spine.
Apply a heat pack, as the warmth will ease the pain and help reduce any muscle spasm.
See your physiotherapist or doctor after one or two days if the pain is still bad.  The sooner you seek advice the sooner you will get better.
Take painkillers at regular intervals (but no more than the recommended dose, and always read the instructions).
Use a relaxation tape if you have one to help calm the mind and ease body tension.
Use this rest period to review your life and try to work out ways to avoid future problems. 
Resolve to improve your posture and, if necessary, to buy a lumbar roll to help you sit properly.
