Sickness bug or dodgy food? Help

[Strawberrycream1]

So I’m never physically sick as in throw up (once in last 8 years). Last night - Christmas Eve about 11pm my stomach started gurgling badly and at 2am I was throwing up violently and again at 4am multiple times. Not diahorrea but loose (sorry tmi), nothing since and it’s now 9am but stomach gurgling like empty.
An hour ago had a mug of boiled water with honey and lemon as throat so sore from being sick and it’s stayed down. Don’t feel sick atm but can’t work out if it’s a bug or something I ate (and now it’s cleared out)
if I now ate say a dry bit of toast and not sick again would you say it was food and I’m ok to see elderly relatives? Aaarrggghh Thank you

ps did a covid test and negative

Try the dry toast

Then an hour later try normal food

If that's all good it looks more likely to be food (did you eat anything unusual?) But I'd ask your elderly relatives how they feel about it, if it was me I would want you to come but keep yourself to yourself eg lots of hand washing and make sure you don't share utensils or cups/glasses unless they've actually been sterilised between use.
But if they have health vulnerabilities they might be more cautious

Thanks, the only thing different I ate was some homemade sausage rolls but they were fully cooked and hot inside?

No one else has eaten them and I’m going to bin them just in case!

Sorry to hear this OP. If you can't be sure what it is I'd stay away from everyone today. It's not fair to pass on anything to anyone, I'd be really cross if guests/family arrived and said they'd been up being sick in the night. You can't take the chance. Hope you feel better soon.

As previous poster said, if you’re in any doubt then keep yourself to yourself. Totally unfair to risk it especially with elderly relatives. It’s only one day and I’m sure they will understand. Go and visit them in a few days once you’re sure all is good
