Or just go to A&E and hope they take you more seriously. My OH had a suspected TIA a couple of years ago, we rang 111 afterwards, first person we spoke to said they'd get a doctor to ring back, which took hours, doctor asked us to drive to his surgery (about 90 mins drive away, the other side of the county), then when we pointed out that R shouldn't be driving if he'd had a TIA and I don't drive, he told R to call our own GP in the morning. When R did, our GP was horrified and sent an ambulance to pick him up within an hour, which is what the first person we spoke to should have done, as a suspected TIA should be followed by an immediate brain scan. And, incidentally, although every medical professional we spoke to throughout the couple of days thought from the symptoms we described that R had had a TIA, it turned out in the end that he'd had a different kind of migraine. So nothing serious at all, and he now has excellent migraine meds.
