Trigger points are palpable nodules found in muscles and usually lie within taut bands of muscle fibres. They are tender on moderate to deep finger pressure and produce what patients sometimes describe as a 'nice pain' or a 'relieving pain' They develop when muscle is put under strain, whether acutely in trauma or through repeated load and are associated with pain and dysfunction in that muscle.
Trigger points are not simply of academic interest. Treating these points (the most common methods are finger pressure and massage) is often very effective in reducing the tension in the muscle, relieving pain and restoring function.
The existence of trigger points in muscles has been documented since the nineteenth century and most likely, long before that. Given the similarity between acupuncture and trigger points, the Chinese were clearly aware of them. However, despite the scientific evidence that trigger points are very common in soft tissue pain conditions they are not routinely used in orthodox medicine. Other than in pain clinics the majority of health professionals who use them are complementary practitioners.
Some, or occasionally, all of these can occur.
Any area comprised of muscle can develop trigger points but some areas do so more than others, particularly those taking the most everyday strains.
Massaging or applying finger pressure to trigger points yourself can be an effective and simple way of relieving the discomfort of simple strains – assuming you can reach the area affected of course.
Treating the trigger points in the muscles at the back of the neck can relieve stiff neck and tension headache. Pressing the trigger points in the muscles either side of the lumbar spine is good for low back pain and massaging the trigger points in the forearm muscles may help relieve tennis elbow.
There are a number of inexpensive books that show the locations of useful trigger points; these are handy to have for self-treatment of muscular pains. However, it's important that you're sure that your condition is a simple muscular strain. Before you start self- treatment or if you have any health concerns, it's a good idea to visit an appropriate health professional.
