Vertigo/ labrynthitis

[Megs64]

Felt a bit ropey when I go up today mild headache,got to the bus stop and bam off balance thing started, got off bus and had to ask someone to help me across the rd. It was awfull,had ear trouble for awhile used to be on buccastem, but haven't had an attack like thus in ages, how can I manage it if it happens again when I'm alone,there may not be anyone about next time it was scary.
