Cricopharyngeal spasm

Cricopharyngeal spasms occur in the cricopharyngeus muscle of the pharynx. These spasms are frequently misunderstood by the patient to be cancer due to the 'lump in the throat' feeling (Globus pharyngis) that is symptomatic of this syndrome. In practice, real lumps in the throat, such as a thyroid cancer, are generally not felt until they impede ingestion of food. This is one of the reasons that a cancer can get so big before it is discovered. In contrast, a cricopharyngeal spasm is an uncomfortable but harmless and temporary disorder.

Causes include stress and anxiety. Other causes are not yet clear. In some cases, eating certain foods may bring on acute spasms, in susceptible individuals. Peanuts, pumpkin seeds and other nuts may trigger these spasms. There are two sphincters in the oesophagus. They are normally contracted and they relax when one swallows so that food can pass through them going to the stomach. They then squeeze closed again to prevent regurgitation of the stomach contents. If this normal contraction becomes a spasm, these symptoms begin.
