Forearm Pain: 7 Essential Facts for Relief and Recovery
Forearm pain—extending from the elbow to the wrist—can be both frustrating and functionally limiting. Whether it’s caused by overuse, nerve compression, or an underlying spinal issue, forearm discomfort often interferes with work, sports, and daily life. At our Long Island-based interventional spine and musculoskeletal practice, we approach forearm pain with a precise, diagnosis-driven strategy rooted in neuroanatomy and function.
Before diving into the causes and treatments for forearm pain, let’s distinguish it from similar terms. Cervicobrachial pain refers to vague discomfort traveling from the neck into the arm, often not confined to a single nerve pathway. Cervical radiculitis implies inflammation of a nerve root without mechanical compression, while cervical radiculopathy indicates compression with predictable neurologic signs. These are discussed more thoroughly in our articles on cervicobrachial pain and cervical radiculopathy.
This page focuses solely on pain localized to the forearm—from elbow to wrist. If you’re looking for help with upper arm pain, elbow issues, or wrist problems, please visit those individual resources.
Common Causes of Forearm Pain
1. Tendon-Related Injuries
- Lateral epicondylitis (Tennis elbow): Affects the extensor tendons on the outer elbow, often causing pain that radiates into the dorsal forearm.
- Medial epicondylitis (Golfer’s elbow): Involves the flexor tendons and leads to pain along the inner forearm.
- Distal biceps tendinopathy: Pain in the upper forearm with resisted elbow flexion or supination.
2. Nerve Entrapment Syndromes
- Pronator syndrome: Median nerve compressed between pronator teres heads, causing anterior forearm aching and hand paresthesia.
- Anterior interosseous nerve syndrome: Pure motor branch of the median nerve—no sensory loss—causing weakness in pinch grip (FPL, FDP).
- Radial tunnel syndrome: Affects the posterior interosseous branch of the radial nerve—dull aching pain in dorsal forearm, often confused with lateral epicondylitis.
- Ulnar nerve compression: May cause pain radiating from elbow into ulnar forearm with numbness in the ring and pinky fingers.
3. Referred Pain from the Cervical Spine
Even when forearm pain seems localized, the true source may be in the neck. C6 and C7 nerve roots commonly refer pain into the forearm, and muscle guarding can mimic tendon pain. If your forearm symptoms are accompanied by neck stiffness or radiating numbness, evaluation for cervical pathology is essential.
4. Myofascial Pain and Overuse
Repetitive activities—typing, lifting, or manual labor—can trigger myofascial trigger points in the brachioradialis, pronator teres, or flexor carpi ulnaris. These can cause aching or shooting forearm pain with palpation or stretch.
5. Fractures, Inflammation, and Other Causes
- Forearm fractures (radius, ulna)
- Compartment syndrome (rare but urgent)
- De Quervain’s tenosynovitis—affecting the radial wrist but may radiate into the distal forearm
- Systemic inflammatory conditions like rheumatoid arthritis or gout
Clinical Evaluation
- Physical exam: Includes resisted motions, palpation, sensory/motor testing, and provocative maneuvers (Tinel’s, resisted supination, pinch grip test)
- Imaging: X-rays (bony injury), ultrasound (tendons and nerves), and MRI (soft tissue, nerve inflammation)
- EMG/NCS: Confirm or localize nerve involvement
- Diagnostic injections: Local anesthetic in suspected structures helps confirm the pain generator
Stepwise Treatment Options
Conservative Management
Physical therapy, bracing, ice/heat, and NSAIDs are first-line. Activity modification and ergonomic adjustments can relieve mechanical strain. Wrist splints and elbow counterforce braces help for tendon overload.
Interventional Pain Procedures
- Ultrasound-guided steroid injections to target tendons or nerves
- Selective nerve root blocks if symptoms suggest cervical origin
- Radiofrequency ablation for chronic tendon pain
Regenerative Medicine
- PRP (Platelet-Rich Plasma): for tendon repair or nerve recovery
- Stem Cells: used off-label for chronic degeneration
- Peptides: for tissue healing support

Frequently Asked Questions
Can forearm pain come from the neck?
Yes. C6–C7 nerve roots often refer pain into the forearm. A cervical disc herniation or foraminal stenosis may be the root cause.
What’s the difference between radial tunnel syndrome and tennis elbow?
Radial tunnel syndrome involves nerve compression; tennis elbow involves tendon overload. Pain location and response to movement tests help differentiate.
How long does forearm tendonitis take to heal?
With rest and therapy, mild tendonitis may improve in 4–6 weeks. Chronic cases may require injections or regenerative options.
When should I see a specialist for forearm pain?
If pain persists beyond 2–3 weeks, limits function, or involves numbness/weakness, consult a musculoskeletal specialist for further evaluation.
