Mrs Y had a very stressful life. Her husband was paranoid, accusing her of infidelity. She complained of a tic in her right cheek and eye and the right side of her neck.
Suspecting hypoglycaemia, I gave her 10ml of 50% glucose solution intravenously. After the injection, the tic improved, along with nausea and numbness of her right second toe!
A fortnight later she reported that "the tic had gone away and she felt better - but they were on holidays as well - and it came back a day before they came home."
