How to Track Shakiness and Tremor Accurately

Shakiness is one of those complaints that behaves itself in the clinic room. You sit down, your hands are still, and the episode you wanted to describe is nowhere to be found. What closes that gap is a record built in the moment: the position your hands were in, the hours since you last ate, the coffee, the inhaler puff, the argument beforehand. Two or three weeks of that turns a vague story into a pattern a clinician can actually reason about, and it often shortens the path to the right tests.

What to Record When You Shake

The single most valuable field is what your body was doing when the shaking started. Note whether it appeared while your hands were completely supported and idle (a rest tremor), while holding a position such as arms outstretched or a cup halfway to your mouth (postural), or during a targeted movement such as writing, pouring, or bringing a spoon to your lips (action or intention). Add the body part: one hand, both hands, head, jaw, voice, legs. Say whether it was visible to someone else or purely an internal buzz or vibration with no outward movement. Log severity as mild, moderate, or severe, using function as your anchor: mild means noticeable but nothing spilled, moderate means handwriting suffers or a cup needs two hands, severe means eating, dressing, or signing your name is not possible. Record start time and how long it lasted (seconds, minutes, hours), and note anything that stopped it, including food, rest, or a warm room.

Triggers and Patterns Worth Watching For

Log caffeine as cups and times, not just yes or no, since a fine fast tremor two hours after a third coffee is a different story from one on waking. Track skipped or delayed meals, because hypoglycemic shakiness usually arrives four or more hours after eating with hunger, sweating, and anxiety, and settles within fifteen to twenty minutes of carbohydrate. Note alcohol, including the timing of the last drink, since withdrawal tremor peaks roughly 6 to 24 hours later, and since essential tremor often quietens briefly after a drink. Add stress, poor sleep, hard exercise, inhaler use, and every dose of daily medication (lithium, valproate, thyroid replacement, stimulants, steroids, some antidepressants). In Trace Health these lifestyle factors sit on the same timeline as the symptom, so a few weeks of entries show whether your shaky days cluster on short nights, on empty mornings, or on days you added a second inhaler puff.

When Shaking Needs Medical Attention

Seek urgent care for tremor with confusion, fever above 38.5°C (101.3°F), a stiff neck, chest pain, fainting, or a resting heart rate persistently above 120. Alcohol withdrawal with sweating, agitation, hallucinations, or any seizure is an emergency. Get an early appointment if tremor is confined to one hand at rest, if your handwriting has shrunk, if walking has slowed or an arm has stopped swinging, or if speech has changed, since these point toward a neurological assessment. Book within a few weeks for new tremor with weight loss, heat intolerance, and palpitations (thyroid), or for tremor that began within days of a new or increased medication. Your clinician will want the pattern of onset, family history, alcohol intake, a full medication list including inhalers and supplements, whether the tremor is worse at rest or on action, and how much it interferes with daily tasks.

Using Trace Health for Tremor Records

One tap logs an episode with mild, moderate, or severe severity, which matters here because tremor amplitude fluctuates hour to hour and averages hide that. Add a short note for the position your hands were in and whether it was visible or internal, and the record keeps the distinction your clinician needs. Because caffeine, meals, alcohol, sleep, stress, and medication doses are charted on the same timeline, you can see the sequence rather than guessing at it. Related entries such as palpitations, dizziness, heat intolerance, brain fog, and fatigue build the fuller picture around the shaking. When it is time for the appointment, export a doctor-ready PDF covering the period in question. Your health data stays on the iPhone by default with optional private iCloud sync, no account is required, and the app runs in 9 languages.

Frequently Asked Questions

How do I tell the difference between rest tremor and action tremor when logging?

Test it deliberately before you log. Rest your hands palm-down in your lap, fully supported, and watch for thirty seconds: shaking here is a rest tremor. Then hold both arms straight out in front of you and watch again: shaking that appears or worsens is postural. Finally reach slowly for a cup or write a sentence: shaking that ramps up as you approach the target is an action or intention tremor. Record which of the three showed it and whether one side was worse. That single line is often the most decisive detail in the whole record.

What does internal tremor mean and is it worth tracking?

Internal tremor is a felt vibration or buzzing inside the chest, abdomen, or limbs with nothing visible on the outside. People with long COVID, dysautonomia, and anxiety describe it often, and it is frequently dismissed because an observer sees nothing. It is worth logging exactly as you would a visible tremor: time, duration, body region, and what preceded it. Note posture changes, since it commonly follows standing, and note heart rate if you can measure it. Over weeks the record may show it clustering with fatigue, palpitations, and poor sleep, which is useful information for your clinician.

Should I stop caffeine to see if it is causing my shakiness?

Discuss changes with your clinician first, particularly if you take regular medication. If you do try it, make the test readable: log your usual intake and tremor episodes for two weeks, then reduce gradually over several days to avoid rebound headache, and log another two weeks at the lower level. Compare the number of episodes and their severity across the two periods rather than judging by a single good day. Keep meals, sleep, and alcohol as steady as you can during the test, since a skipped lunch can easily mimic a caffeine effect and confuse the result.

“Finally an app in which I can collect and analyse all my symptoms. And that reminds me to log them.” (sunsoul01, Austria)
“Ok so I try so hard to track symptoms but apple health doesn’t have a widget for that and it’s kind of a pain to track down every little thing… Now this app!!!! Everything is right there, there’s widgets, it’s fast and simple and syncs! I freaking love this app! I’m still playing with it so I haven’t seen if it has a “how are you feeling right now” feature but it is everything I have ever wanted the symptoms on health to be!” (grofica82, United States)
