Last Friday my wife experienced an episode of dizziness and tingling in her left fingers and left toes and foot. She is still in hospital and is being investigated for a mini stroke but all tests including 2 x ct scans, Doppler ultrasound of caratoid arteries, numerous physical examinations, eye and coordination tests, blood tests, ect, bp have all shown nothing. She is an extreme worrier and has had rather extreme family problems over last few months and has been worrying unbelievably over this. Can you indicate whether this extreme stress and worry could cause these symptoms.
