How to get rid of muscle knots
The next morning you wake up and find that the back of your shoulder blade feels stiff. When you rub your shoulder muscles, it feels like you’re poking a small ball of gum under your skin. Every time you try to move it, the area feels tight, with a bit of pain.
Over the next few days your back will slowly relax and eventually your shoulder will feel normal again. However, it’s probably something you’ll want to avoid or minimize if possible in the future. So what was up with that muscle knot?
Some of the most common questions I’ve heard during my years as a personal trainer and researcher in the field involve muscle knots. What are they and how can you get rid of them when they appear?
What are muscle knots?
When your muscle becomes damaged – even a little – it can lead to inflammation in the muscle ligaments and the overlying fascial layer. And that lump of inflamed tissue is a myofascial trigger point. The small lumps are usually tender to the touch and can limit your range of motion or cause pain with various movements. Muscle knots don’t show up on medical imaging scans, and researchers are still trying to figure out the exact physiological mechanisms within the muscle that cause this reaction.
Myofascial trigger points tend to develop when a muscle is irritated by a new or more strenuous than usual repetitive movement. For example, during a particularly intense day of exercise, you may develop knots in the muscles that you worked the most. They can also show up when you introduce a new movement pattern into your daily workout.
Imagine adding a few days of running to your typical weekly routine of just lifting weights. Since running is a new movement, you may notice some knots in your calves that have asked for a lot of new work.
However, you don’t have to be a gym rat to be familiar with muscle knots. For example, if you sit hunched over a computer all day, you may notice knots developing in your upper back and shoulders. Most people wouldn’t find sitting at a desk tiring, but holding one position for hours does put a strain on your muscles. Enter muscle knots.
How do you get rid of muscle knots?
For example, if you have knots in the quadriceps muscle group at the front of your thigh, you can lie on a foam roller and gently roll your leg back and forth on it. Alternatively, you can roll the machine up and down the muscle group and keep the pressure within your comfort zone. Because you’re applying as much pressure as you like, you can work within your own pain tolerance — an advantage since relieving myofascial trigger points can be uncomfortable. You can use this technique anywhere you have muscle knots.
While they can be annoying, muscle knots are nothing to worry about. Remember that sticking to your exercise habits and exercise throughout the day can help prevent knots from developing in your muscles at all. If you notice muscle knots emerging, simply stretching at the end of the day or performing some self-myofascial relaxation techniques are simple, effective ways to relieve this problem and prevent future problems.
