the chronic parasympathetic person becomes susceptible to osteoarthritis, angina, anxieties and panic attacks, asthma, heart attacks, depression, severe allergies, skin conditions, and cardiac arrhythmias. The cause of the stress could be anything. Emotional stress, dietary stress and physical stress are all common and they all count. A muscle correlation to the adrenals is the sartorius muscle which connects at the pelvis and the medial knee. If it neurologically weakens the sacro-iliac joint on the affected side will go posterior and medial knee stability will be compromised. If that is the case all it takes is a twisting or rotation of the joint and it could be injured. Even in a contact sport like football, most knee injuries are not contact induced, but rather the wrong movement creating the injury. In other words, when the body is in a stress response it is an accident looking for a place to happen. The chronic parasympathetic person becomes susceptible to osteoarthritis, angina, anxieties and panic attacks, asthma, heart attacks, depression, severe allergies, skin conditions, and cardiac arrhythmias. If this person got cancer it would be of the non solid type like leukemia. 10 Their immune systems tend to be overactive. Since parasympathetic people can be calcium and protein deficient, they can also experience musculoskeletal discomfort. When they get to the point of severe back pain they will usually display bilateral sacroiliac weakness which also weakens the gluteus maximus muscles. These are major antigravity lifting muscles. When weak, the person will lean way forward when sitting and then push themselves up. In a grocery store they are usually leaning over their carts to take the pressure off their backs.
