What Causes Muscle Spasm in Fibromyalgia?
There are certain reasons why your muscles undergo contraction. At times, it may even happen without any apparent reason even if it does happen frequently. For most people, muscles contract because of extreme physical activities. Some experience muscle spasms due to postoperative outcome and injury etc. However, fibromyalgia muscle spasm is possibly a result of myofascial trigger points (TrPs) or muscle knots.
TrPs, like its second name, are almost literally knots in the muscles. They develop when muscle tissues heal abnormally, usually after a muscle injury like a strain, forming a hard nodule. TrPs are the main symptom that characterize myofascial pain syndrome (MPS). It is so common for MPS and fibromyalgia to coexist in a patient that some doctors believe that both conditions are the same illness.
TrPs can hurt when you apply pressure on it. Interestingly, it causes referred pain in another part of your body which is seemingly unrelated to the origin’s point. For instance, a muscle knot on the neck can lead to pain at the top of the head and under the eyes. In fact, a study found that by influencing TrPs, researchers were able to recreate fibromyalgia pain in other parts of the body. The study concluded that TrP is the reason behind muscle spasm and suggested that it can also be the reason behind fibromyalgia for some people.
Nevertheless, there are also other factors that can cause muscle spasm such as over-reactive nerves and nutrient deficiencies.
