Hi, I have had muscle twitching in both legs for 14 hours now. I am worried it's something serious.
JA: What seems to make the symptoms worse or better? Have you noticed any swelling?
Customer: Nothing affects them, both legs just keep twitching
JA: Anything else in your medical history you think the Doctor should know?
Customer: I have been feeling anxious but not sure if the muscle twitches are related
Customer: replied 19 days ago.
I'm concerned about motor neurone disease, I've never had this twitching before

Muscle twitching is rarely serious (unless you search on Google)!

Anxiety is a very common cause of muscle twitching.

Please read this authentic article and under the heading:

Fasciculations in healthy subjects

It says;

Fasciculations can also be found in individuals with no neurological disease. Reed and Kurland warned that the presence of fasciculations was not necessarily a prelude to the onset of progressive and lethal disease, due to the involvement of the lower motor neuron (ALS).

These authors, in agreement with others, concluded that physical exercise, stress, fatigue, and caffeine abuse can precipitate or aggravate this picture.

Muscle fasciculation or muscle twitching is caused by minor muscle contractions in one particular area or the persistent and uncontrolled twitching of a muscle group in the distribution of a single nerve fiber or filament. Usually, they are benign and resolve on their own, but persistent flutter may need following investigations;

1) electromyography (EMG)

2) nerve conduction velocity (NCV)

3) blood electrolytes like calcium, magnesium, potassium, sodium, etc

4) thyroid and parathyroid function tests

5) blood chemistry and complete metabolic profile

The common causes can be;

1) Idiopathic; no cause is ascertained and the majority falls in this group.

2) Increased caffeine intake

3) Increased alcohol intake

4) Medications

5) Deficiency in diet and nutrients / minerals

6) Some neurological diseases; uncommon

If I had MND would I have other symptoms or could both legs twitching be the start of it, I'm very worried
Customer: replied 19 days ago.

MND requires months of investigations by an experienced neurologist and medical imaging like MRI.

Twitching alone is never a diagnostic of MND as mentioned above.

Diagnosing yourself by Google is the cause of your underlying anxiety.
