Hives from Saki? HELP!?

Yesterday I was at a hibachi grill and someone next to me spilt their saki drink and it got all over my feet. They started itching and I got hives all over them. Its been almost 24hours and the hives are still there and itch! I don't drink saki it only spilt on me. Why do I have these hives and what will make them go away? Thanks.
