What you're describing — hands that shake when you try to hold them still or perform a deliberate action — is called action tremor or, most commonly, Essential Tremor (ET).

Here's a breakdown:

What Is It?

Essential Tremor (ET) is the most common movement disorder, affecting ~1% of the general population and up to 5% of people over age 60. It is characterized by:

Tremor that appears when holding a posture (e.g., arms outstretched) — called postural tremor
Tremor that appears during voluntary movement (e.g., reaching for something) — called action/kinetic tremor
The tremor is NOT present at rest — this is the key distinguishing feature

This perfectly matches what you described: trying to hold your hand firm and still, but it shakes anyway.

How It Differs from Other Tremors

Type	When it occurs	Common Cause
Essential tremor	During action/posture (holding still)	Most common; often runs in families
Parkinson's tremor	At REST (pill-rolling), quiets with movement	Parkinson's disease
Cerebellar tremor	Worsens as hand approaches a target	Cerebellar damage
Physiologic tremor	Fine tremor, normal; worsened by caffeine, anxiety, fatigue	Normal variant

Key Features of Essential Tremor

Frequency: 6–10 Hz (relatively fast)
Location: Usually both hands/arms; can also affect the head and voice
Family history: Often positive (sometimes called "familial tremor")
Alcohol effect: Classically improves temporarily with small amounts of alcohol
Does NOT indicate Parkinson's — though both involve shaking, they are different conditions

What Makes It Worse?

Anxiety or stress
Caffeine
Fatigue
Certain medications (lithium, valproate, stimulants)
Hyperthyroidism (a treatable cause to rule out)

Treatment Options

If the tremor is bothersome:

Propranolol (beta-blocker) — first-line medication
Primidone (anticonvulsant) — also first-line
Avoiding triggers (caffeine, stress)
In severe cases: deep brain stimulation (DBS)

Bottom line: Hands that shake specifically when you try to hold them firm or use them (but are calm at rest) is the classic picture of essential tremor. It's common, benign, but can range from barely noticeable to functionally limiting. If it's interfering with daily tasks, a neurologist can confirm the diagnosis and discuss treatment.

Is it harmful. Age 15. It’s just palm

Short answer: No, it is not harmful. Essential tremor is a benign condition — it does not damage the brain, does not progress to something dangerous, and does not shorten life.

Here's what's relevant for a 15-year-old:

Is it dangerous?

No. Essential tremor causes no structural brain damage and is not a sign of a serious disease. The textbook specifically states:

"Many cases are mild, do not cause any functional impairment, and require no treatment other than reassurance." — Harrison's Principles of Internal Medicine 22E

Can it happen at age 15?

Yes. ET can present in childhood, though it becomes more common with age. In younger people it is often milder and may stay mild for years or decades.

Common causes of tremor in teenagers to consider

A few things can trigger or worsen an otherwise minor tremor at that age:

Cause	Notes
Caffeine	Energy drinks, coffee, soda — very common trigger in teens
Anxiety / stress	Extremely common at 15; activates the nervous system
Fatigue / poor sleep	Makes any tremor worse
Low blood sugar	Skipping meals
Hyperthyroidism	Overactive thyroid — easy to rule out with a blood test
Familial ET	Runs in families; benign

What to do

No urgent action needed if the tremor is mild and only in the palms during action
Reduce caffeine if consumed regularly — this alone often helps significantly
See a doctor once just to rule out thyroid issues or other simple causes — a basic blood test covers this
No need to worry about Parkinson's or anything serious at age 15

Bottom line: A palm tremor that only shows up when trying to hold still, at age 15, is almost certainly benign — most likely a physiologic or essential tremor, possibly worsened by caffeine, stress, or fatigue. It's worth one doctor's visit to confirm, but there is nothing to be alarmed about.

Can a person become doc with it

Yes, absolutely. Having essential tremor does not disqualify anyone from becoming a doctor.

Here's the reality:

Most medical specialties are unaffected

The vast majority of medical work does not require perfectly steady hands:

Physician (general medicine, psychiatry, pediatrics, radiology, pathology, internal medicine, dermatology) — tremor is completely irrelevant
Diagnostics, clinical reasoning, patient communication — these are the core skills of most doctors

Surgery is a specific consideration — but still often possible

Even surgeons with mild essential tremor practice successfully. A few points:

Mild tremor (like what you're describing — only when consciously holding still) is often not noticeable during actual procedural work, because active, purposeful movement can actually suppress it
Many surgeons have some degree of physiologic tremor and compensate naturally
If tremor were severe enough to be a problem, medication (propranolol) taken before procedures can reduce it significantly — some surgeons already do this
Robotic surgery (e.g., da Vinci system) electronically filters out hand tremor — this technology is increasingly common

Famous example

Many physicians and surgeons throughout history have practiced with tremor conditions. It is not a barrier recognized by medical licensing boards in most countries.

What actually matters for becoming a doctor

Academic performance
Clinical knowledge and judgment
Communication with patients
Ethical practice

A mild palm tremor at age 15 that only appears when holding still is nowhere near an obstacle to a medical career — including surgery if that's the goal.
