Achy legs noro?

Hi all,

I have been very anxious recently, and my legs have been shaking quite a lot (this is one of my biggest anxiety symptoms) and my whole body has been quite tense. This morning my legs have been kind of aching.

I am VERY anxious about catching noro, and while I have not been exposed as far as I know (besides the exam hall, public transport and restrooms), I just can't rest...

Could the achy legs be a symptom? I am trying to think back, and I am pretty sure I have felt like this earlier, but my brain has been in overdrive, and I am so scared of catching noro... I am very diligent with hand washing, always washing it twice, but I feel like you could never really know. Also ordered a pizza yesterday, which I am so scared it was contaminated
