Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

The double crush phenomenon occurs when a nerve is compressed in the neck, making it more susceptible to milder compression at other sites.

◐Partially SupportedTinel's sign can indicate irritable median nerve due to carpal tunnel syndrome.

◐Partially SupportedWinging of the scapula during a push-up can indicate issues with the upper cervical nerve root and long thoracic nerve.

◐Partially SupportedAn unstable shoulder fracture treated with a sling and pendulum exercises can cause nerve damage due to arm weight.

◐Partially SupportedNumbness and tingling upon flexing and holding the elbow can indicate a secondary issue related to the ulnar nerve.

◐Partially SupportedThe sensory terminal branch of the radial nerve can cause numbness and tingling in the hand when tapped or compressed.

◐Partially SupportedThe ulnar nerve is involved at the elbow in 98% of cases, with involvement further down the forearm being rare.

◐Partially SupportedThe simultaneous occurrence of multiple nerve lesions (six or more) is required to explain symptoms typically attributed to a single cause, except in cases like parsonage Turner syndrome.

◐Partially SupportedNumbness on the back of the hand combined with neck stiffness can indicate radial nerve involvement.

◐Partially SupportedAsymmetry in neck rotation or extension can indicate nerve pinching originating from the neck.

◐Partially SupportedA slipping ulnar nerve can cause snapping nerve syndrome in throwing athletes, leading to irritability and loss of fine motor control.

◐Partially SupportedOverdeveloped triceps can press against the ulnar nerve, causing a form of cubital tunnel syndrome.

◐Partially SupportedScapular thoracic bursitis can develop from lifting weights, especially after a long break, causing pain in the upper trapezius, periscapular, and rhomboid muscles.

◐Partially SupportedParsonage Turner syndrome is an inflammation of the brachial plexus nerves, likely viral, characterized by acute pain followed by weakness and numbness.

◐Partially SupportedIrritation above the elbow may originate from the neck, while irritation below the elbow could stem from the neck or local issues.

◐Partially SupportedPain originating from an intrinsic shoulder problem typically stays below the deltoid muscle and rarely extends below the elbow, whereas pain radiating below the elbow suggests a neck origin.

◐Partially SupportedParsonage Turner syndrome is typically self-limited and often treated with steroids for complete recovery.

◐Partially SupportedThe 'double crush' phenomenon occurs when a nerve is compressed in the neck, making it more susceptible to milder compression at other sites.

◐Partially SupportedLong thoracic nerve palsy can lead to scapular winging, where the scapula cannot support the shoulder and arm weight due to muscle weakness.

◐Partially SupportedCompression of the C7 nerve root can cause deep scapular pain and can be mistaken for scapulothoracic bursitis.

◐Partially SupportedPatients with a double crush phenomenon may experience residual nerve pain in the upper limb even after carpal tunnel release surgery.

◐Partially SupportedShoulder pain may originate from the neck.
