Ever hear someone else groaning in a yoga class? Or maybe that you? Yes, when you are stretching a tight area of your body, you can experience quite a bit of sensation. And while healthy stretches can provoke an intense feeling, it’s a good idea to pay attention to the type of sensation you’re experiencing because this may indicate you should back off the stretch.
As we discussed in previous posts (see What is Flexibility, Anyway?), stretching a muscle or muscle group and fascia is healthy and beneficial, but stretching a tendon or ligament can cause an injury, such as a tear, inflammation, tendonitis, or tendonosis. In addition, compressing a joint when you are stretching can pinch the tissues caught between the bones closing in toward each other, which cause pain and lead to inflammation. So it’s important to learn to tell the difference between the sensations of healthy stretch of a tight muscle versus the pain, pinching, or “smashed together” feelings that are warnings of potential injury.
Healthy Sensations. You will feel generally feel healthy stretch of a muscle in the mid-portion of a muscle, farther away from the tendons and ligaments are located close to joints. A good place to become familiar with this type of sensation is the hamstring muscle at the backs of your thighs, which you stretch in Standing Forward Bend (Uttanasana) and Reclined Leg Stretch (Supta Padangusthasana). As most of you know, the intensity of the stretch sensation there can be quite strong, and yet it generally doesn’t mean you are injuring yourself. So when you experience this type of sensation, as long as the stretch is a moderate one, take a deep breath and try to relax into the stretch.
Unhealthy Sensations. You will generally feel an unhealthy stretch of muscle, tendon, or ligaments closer to a joint, such as your hip, knee, shoulder or elbow joint. And the quality of feeling will be different than a healthy stretch, maybe burning, sharp, stabbing, throbbing, or tearing in quality. For example, with the hamstring muscles, if you feel a tender burning sensation up toward your buttocks, this could be an indication you are overstretching the attachments. In all cases, when you experience these types of sensations, you should immediately back off the stretch if possible to see if that helps. If not, come out of the pose entirely.
It is possible to feel this burning, sharp, stabbing, throbbing, or tearing sensation in the muscle body as a result of a sudden, intense, quick stretch, so that is why we always recommend moving slowly and with in control into your stretches.
Joint Compression. Sometimes when you are stretching a muscle, the joint that is bending can become compressed. For example, when you deeply bend your knee joints, as in Child’s pose (Balasana), the tissues at the back of the knee joint can become pinched together. This is potentially dangerous because the compression could produce tissue damage and inflammation, or even could injure nerves or blood vessels, leading to acute or chronic pain and dysfunction.
In general what you’ll feel when a joint is compressed is either a sensation of muscles, skins, tendons, fascia, and/or bones being “smashed together” or a pinching sensation. For example, some of less flexible folks feel smashed together or pinching sensations in our front hip when doing Extended Side Angle pose (Utthita Parsvakonasana) with our hand on the floor. Both of these sensations indicate that you are overdoing it, and you should back off the stretch, possibly by adding a prop. If you can’t eliminate the joint compression, come out of the pose.
Compression can also put pressure on blood vessels and nerves, so if you have an unusual pressure sensation in the joint or feel numbness and tingling downstream from the compressed area, that is an indication that you are overdoing it and should back off the stretch or come out of the pose.
