Why does my back/neck go into spasm?
When your brain is aware of an area of concern, its primary objective is to slow you down and limit movement so that it can assess the damage. Your muscles go into spasm to protect themselves from causing further muscle strain or injury. The good news is that an injury or strain to the soft tissue (Muscle, tendon, ligament) usually heals enough in a week or two for the spasms to resolve.
Spasm which do not resolve after 1-2 weeks may be indicative of underlying anatomical issues, but these are less likely to have a sudden onset as described above and usually occur progressively over time. A Physiotherapist should be consulted if there are continuing episodes of spasms and pain.
The best thing to do when a spasm hits:
Your first goal is to get the muscles to relax and in doing so relieve the pain experienced.
Short period of rest:
While rest and taking it slightly slower is important, it is essential that you don’t just lie down and stop moving. While pushing into and through pain can delay recovery, not moving at all can do the same. Focus on moving as much as tolerated – this might be hugging the knees or rolling the shoulders. Take a short walk which helps to promote blood flow and aid in the healing process. Just make sure not to overdo it.
