My 18 yr old dd has had a few experiences of momentarily loosing eyesight and hearing. She does not loose consciousness but feels very week after. Of the three times she has gone to A&E, they say she is fine with stats and hears nothing again and G.P runs bloods, nothing wrong. Should she go to A&E tonight to rule out stroke ? No history of stroke, no contraception. Sweats profusely, painful periods.
