Your voice needs care, especially if you use it daily

Hoarseness means the vocal cords are not closing and vibrating the way they normally do. Swelling, a small growth on the cord, dryness, muscular strain, inflammation from reflux, or a nerve that is not working fully can all produce a similar sound. The voice itself cannot tell you which of these it is.

This is why the three-week mark matters. A voice that goes hoarse after a cold or a long weekend usually recovers within days. Hoarseness that carries on beyond roughly three weeks should be looked at, so that the cause is identified rather than assumed.

Teachers, lawyers, broadcasters, singers, sales and call-centre staff use the voice the way an athlete uses a joint. The load accumulates. The voice starts clear in the morning, then thins, catches or drops away later in the day, and takes longer each week to come back.

Sustained strain can leave marks on the vocal cords, such as nodules or a polyp, and other lesions such as cysts can produce the same pattern of fatigue. Air conditioning, low humidity, dehydration and speaking over background noise add to the load. Looking at how the cords actually move is the difference between guessing at a pattern and knowing what is behind it.

A constant need to clear the throat, a voice that is at its worst on waking, and a sense of something sitting in the throat often point away from the throat itself. Acid and digestive enzymes reaching the larynx from below can irritate the lining without ever causing heartburn. This pattern is called laryngopharyngeal reflux.

The sensation of a lump when there is no pain and swallowing is normal is known as globus. It is common, often persistent and uncomfortable. In many people no structural cause is found, and reflux or muscular tension is the usual explanation. Endoscopy, together with an assessment of the upper oesophageal area, helps separate reflux from other explanations so that treatment can be directed accordingly.

Swallowing is a fast sequence of muscles and nerves firing in order. When food catches, when drinks make you cough, or when meals take noticeably longer than they used to, part of that sequence needs to be observed rather than described from memory.

Difficulty swallowing has a wide range of causes, including muscular, neurological and structural ones. Part of a proper assessment is to look for those causes calmly and early, so that what remains can be treated with a clear picture in hand.
