Here is a comprehensive answer on bilateral (B/L) upper limb pain - its major causes organized by category:

Bilateral Upper Limb Pain - Causes

This is a classic exam question. The causes are best grouped by the anatomical level or underlying mechanism:

1. Cervical Spine / Spinal Cord Pathology (MOST IMPORTANT)

Condition	Key Features
Cervical Spondylosis / Cervical Myelopathy	Neck pain + B/L UL pain, numbness, weakness, loss of dexterity; lower limb stiffness; Lhermitte sign; increased LMN signs in arms, UMN in legs
Cervical Spinal Stenosis	Similar to myelopathy; MRI is diagnostic
Syringomyelia	Cape-like dissociated sensory loss (pain & temp lost, touch preserved); wasting of intrinsic hand muscles; B/L UL pain; associated with Arnold-Chiari malformation
Cervical disc herniation (large central)	B/L radicular arm pain

Goldman-Cecil Medicine: "Symptoms include neck pain; unilateral or bilateral upper limb pain; upper limb weakness, numbness, and loss of dexterity" - referring to cervical myelopathy/spondylosis.

2. Neurological Causes

Condition	Key Features
Motor Neuron Disease (AML/ALS)	Progressive weakness + pain, B/L involvement
Peripheral neuropathy	Diabetes, vasculitis - can be bilateral
Diabetic cervical radiculoplexus neuropathy	Begins focally, evolves into multifocal or bilateral condition with pain + weakness
Lyme disease ("Dangling arm syndrome")	B/L motor cervical radiculoplexus neuropathy; proximal arm weakness with acute pain, bilateral in ~60%
Guillain-Barre Syndrome (GBS)	Ascending B/L weakness + pain (back/limb pain common early)

3. Vascular Causes

Condition	Key Features
Aortic dissection (Type A)	Severe chest/back pain + arm pain; can involve bilateral subclavian/brachial arteries; pulse deficit; neurologic syndromes
Subclavian artery occlusion (bilateral)	Rare; ischemic arm pain
Bilateral upper limb DVT	>90% associated with indwelling catheters

4. Rheumatological / Musculoskeletal Causes

Condition	Key Features
Polymyalgia Rheumatica (PMR)	Bilateral shoulder girdle + proximal arm pain/stiffness in elderly; elevated ESR/CRP
Rheumatoid Arthritis	Bilateral joint pain, swelling, morning stiffness
Fibromyalgia	Widespread bilateral pain including arms
Thoracic Outlet Syndrome (bilateral)	Compression of brachial plexus/vessels; paresthesias + pain in arms

5. Referred Pain

Condition	Key Features
Angina / Myocardial Infarction	Classically left arm, but can radiate to both arms; associated with chest pain, dyspnea
Diaphragmatic irritation	Referred shoulder/arm pain

6. Metabolic / Systemic

Condition	Key Features
Hypoparathyroidism / Hypocalcemia	Tetany, paresthesias, cramps bilaterally
Hyperventilation syndrome	Bilateral tingling/pain in hands and arms
Peripheral neuropathy	Diabetic, alcoholic, B12 deficiency

Key Mnemonics for Exam

"CAMPS" for bilateral UL pain at spinal level:

Cervical spondylosis/myelopathy
Arnold-Chiari/Syringomyelia
Motor neuron disease
PMR (polymyalgia rheumatica)
Syrinx / Spinal cord compression

Classic "Must-Know" Exam Association

Bilateral UL pain + SUSPENDED SENSORY LOSS (pain/temp lost, touch preserved)	= Syringomyelia (cape-like distribution)
Bilateral UL pain + neck pain + lower limb UMN signs	= Cervical myelopathy/spondylosis
Bilateral UL pain + shoulder girdle stiffness in elderly	= Polymyalgia Rheumatica
Bilateral UL pain + ascending weakness	= Guillain-Barre Syndrome
Bilateral UL pain + severe chest/back pain + BP difference	= Aortic Dissection
