But pronunciations with a silent p in pn (as also in pneumo-) are common ( or ), as are those with the stress on the first syllable ( or ). In English, the various -pnea-suffixed words commonly used in medicine do not follow one clear pattern as to whether the /niː/ syllable or the one preceding it is stressed; the p is usually expressed but is sometimes silent depending on the word. The following collation or list shows the preponderance of how major dictionaries pronounce and transcribe them (less-used variants are omitted):

Myokymia is an involuntary, spontaneous, localized quivering of a few muscles, or bundles within a muscle, but which are insufficient to move a joint. One type is superior oblique myokymia. Myokymia is commonly used to describe an involuntary eyelid muscle contraction, typically involving the lower eyelid or less often the upper eyelid. It occurs in normal individuals and typically starts and disappears spontaneously. However, it can sometimes last up to three weeks. Since the condition typically resolves itself, medical professionals do not consider it to be serious or a cause for concern. In contrast, facial myokymia is a fine rippling of muscles on one side of the face and may reflect an underlying tumor in the brainstem (typically a brainstem glioma), loss of myelin in the brainstem (associated with multiple sclerosis) or in the recovery stage of Miller-Fisher syndrome, a variant of Guillain–Barré syndrome, an inflammatory polyneuropathy that may affect the facial nerve.Myokymia in otherwise unrelated body parts may occur in neuromyotonia. Causes
Frequent contributing factors include: too much caffeine, high levels of anxiety, fatigue, dehydration, stress, overwork, and a lack of sleep. Use of certain drugs or alcohol may also be factors, as can magnesium deficiency. It can be also seen in patients with multiple sclerosis.
