Why your fingers are cold all the time. No, it's not just the weather - it can be a sign of worrying health conditions, reveals DR ELLIE

I am 94 and in the past year have developed sensitive fingertips. Dr Ellie Cannon replies: Sensitive fingertips may be due to peripheral neuropathy, a condition where the nerves don’t function as they should. There’s also a condition called cyclical vomiting syndrome, which responds to migraine medication sumatriptan – especially used as a nose spray. The antidepressant amitriptyline may also ease chronic vomiting – the bonus is that it can help patients cope with the horrible psychological burden of the constant nausea. I know from seeing so many patients with dizziness how disabling it can be when it’s longer term: stopping people driving, walking safely and even just leaving the house.
