Hiccups as a Rare Presentation of Thyrotoxicosis Triaged by an Epidural Steroid Injection.

Thyrotoxicosis manifests when excess levels of thyroid hormone act on different tissues throughout the body.

It has been theorized that high levels of thyroxine can irritate the neuroanatomical hiccup center leading to persistent hiccups.
