One source of snapping scapula is when the muscles underneath the scapula (the subscapularis muscle) atrophies. This causes the scapula to become very close to the rib cage, eventually causing rubbing or bumping during arm/shoulder movement. Another cause is bursitis, which is when the tissues between the shoulder blade and thoracic wall ...
The underlying cause is unclear. Some believe the pain may be from the chest wall or irritation of an intercostal nerve. [1] [2] Risk factors include psychological stress. [2] The pain is not due to the heart. Diagnosis is based on the symptoms. Other conditions that may produce similar symptoms include angina, pericarditis, pleurisy, and chest ...
Pectoralis minor syndrome (PMS) is a condition related to thoracic outlet syndrome (TOS) that results from the pectoralis minor muscle being too tight. [1] PMS results from the brachial plexus being compressed under the pectoralis minor [2] while TOS involves compression of the bundle above the clavicle. In most patients, the nerves are ...
Medical history (the patient tells the doctor about an injury). For shoulder problems the medical history includes the patient's age, dominant hand, if injury affects normal work/activities as well as details on the actual shoulder problem including acute versus chronic and the presence of shoulder catching, instability, locking, pain, paresthesias (burning sensation), stiffness, swelling, and ...
The severity and appearance of the winged scapula varies by individuals as well as the muscles and/or nerves that were affected. [2] [3] Pain is not seen in every case. In a study of 13 individuals with facioscapulohumeral muscular dystrophy (FSHD), none of the individuals complained of pain. Fatigue, however, was a common characteristic and ...
The nerves in your lower neck - particularly the areas of your C6 and C7 vertebrae - refer right into the middle of your shoulder blade. So if you notice the pain easing when you sit upright or ...
Hyperventilation syndrome (HVS), also known as chronic hyperventilation syndrome (CHVS), dysfunctional breathing hyperventilation syndrome, cryptotetany, [1] [2] spasmophilia, [3] [4] [5] latent tetany, [4] [5] and central neuronal hyper excitability syndrome (NHS), [3] is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly ...
Kehr's sign is a classic example of referred pain: irritation of the diaphragm is signaled by the phrenic nerve as pain in the area above the collarbone. This is because the supraclavicular nerves have the same cervical nerves origin as the phrenic nerve, C3, C4, and C5.
