I have stomach bug phobia as well...just being in contact with someone who has had it recently sends me into a worry tailspin.
Pvc's and racing heart can be from being sick...it puts extra stress on the body and if you are anything like me, the mind!
I don't know if you remember, but a couple of months back, my daughter had the stomach flu, and I got so worked up about
getting it. Every little twinge and sensation in my body threw me into full alert
. I couldn't sleep and kept waking up thinking 'This is it!'
I did end up getting it, but it wasn't as bad as I anticipated...and my anxiety over it was way worse (and out of proportion) to the actual illness.
Try to just get through it as best you can. Our bodies are strong, and made to fight off these things, but you may feel the effects, like the increase in pulse, BP, Pvc's, fever, ect. These are all unpleasant, but to be expected.
Take care of you and your little one with lots of rest, liquids and tylenol
