The duration of back muscle spasms can vary depending on the severity of the spasm and the underlying cause, and can span between a few minutes to a few hours per episode.
A back muscle spasm is an involuntary contraction of one or more muscles along the spine. This can lead to muscles becoming tense or sore.
Spinal stenosis is the narrowing of the spinal canal. The spinal canal has a tube-like structure that is formed by the hollow spaces in between each vertebra.
Spasms in the back do not always represent a cause for concern, regardless of the region they affect. In many cases, they tend to disappear on their own with sufficient rest.
A back muscle spasm can last anywhere between a few seconds and a few minutes.
