Living with Hereditary thermosensitive neuropathy

A rare inherited nerve condition with temporary muscle weakness and tingling brought on by fever.

Understanding Hereditary thermosensitive neuropathy

Hereditary thermosensitive neuropathy is a rare inherited nerve condition with temporary episodes of weakness triggered by fever.

Episodes include muscle weakness that spreads upward, tingling or pins and needles (paresthesias), and loss of reflexes. They reverse after the fever, and may occur with or without pressure palsy. It can start from childhood to adulthood.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Based on the summary, episodes can include:
