Elbow, Wrist & Hand
Ganglion Cyst
Also called: Wrist/hand cyst, Bible bump
A fluid-filled cyst ballooning from a joint capsule or tendon sheath — most often the back of the wrist. Benign, frequently fluctuating in size, sometimes achy with load. Historically thumped with a Bible; better managed with patience, since about half resolve on their own.
Common signs
- A smooth, rounded lump at the wrist (back or palm side) or finger base
- Size varies with activity; may transilluminate (glow with a penlight)
- Ache with loaded wrist extension (push-ups) in some
- Often painless entirely
Seek help now if
- A hard, fixed, irregular, or rapidly growing mass (different workup — don't assume cyst)
- Numbness/tingling from nerve pressure
- Redness, warmth, fever
Any of these: call 911 or get to an emergency room first. Everything else can wait.
What to do first
- Confirm it's a ganglion by exam (± ultrasound if atypical)
- If painless: observation is legitimate treatment — half resolve
- If achy with load: modify wrist extension loading (push-up handles, wedges) and support briefly
If it's become chronic
- Persistent symptomatic cysts: aspiration offers relief with a real recurrence rate; surgical excision is more definitive with a smaller one
- Do not smash it — tissue trauma without cure
- Recurrent cysts after removal are known behavior, not failure
Natural healing options we use
- Load modification and wrist-mechanics care
- Manual therapy for surrounding tissues; chiropractic care for carpal mechanics
- Compression support during aggravating tasks
About imaging
Ultrasound confirms cystic nature when uncertain; MRI for atypical masses.
Daily self-care
- Neutral-wrist push-up modifications
- Watchful waiting with monthly size notes
- Evaluation for any mass that behaves differently
