What causes “knots” or muscle spasms in your upper back and shoulder?
A knot is a contraction or spasm in the muscle. The most common cause is over-work. It’s not necessarily that YOU are doing too much work but you are overworking some of your muscles.
Those muscles get protective. To protect themselves and prevent injury or ripping, they go into a type of contraction. There are different types of contractions.
What is a “contraction”?
Make a fist with your hand. Your hand gets tight and loses color. That is a good example of a muscle contraction.
If you can “pump up” your bicep or upper arm muscle between your elbow and shoulder, that is another example of a contraction.
There is less blood flowing through the contracted muscle. The muscle feels tight in that area or feels like a “knot” or hard. A muscle spasm, contraction or knot are basically all the same.
And they can hurt or burn. They can be extremely annoying and make it hard to work or sleep.
The good news is: Muscles are almost always to blame and muscles are treatable. You just have to know which muscles to work on and how to prevent the knots in your shoulder and back from returning.
