Ask a Neurologist and Get an Answer ASAP
Twitching of a muscle or muscles is what we call "fasciculations". They are quite common among otherwise healthy individuals.
They are not a classic feature of Parkinsons (PD) You might be thinking of tremors, which are more rhythmic and pronounced movements, and ate common in PD.
You are also too young to be worried about PD and motor neuron diseases. :-)
Fasciculations are typically associated with stress, fatigue, anxiety, poor sleep and sometimes too much caffeine.
They usually resolve within a few days to weeks, though often recur in other places if the underlying stress or fatigue, etc, are not adequately addressed.
However this twitch is constant and been going on for around 5 days and showing no signs of resolving. It occurs when my hand is at rest.
How long do you believe this twitching will continue?
Days to weeks. It's a sign of neuromuscular irritability in that particular motor unit....sometimes roveruse or strain.
Sometimes triggered by overuse or strain.
The hands, legs and face (e.g the eyelids) are the most common sites.
Hi, the twitching still hasn't resolved and happens when my thumb is relaxed.
Can you please advise me on how long I should give it before I visit a GP? Its been 7 days so far.
