You should call immediately your family doctor, sometimes instead of syringes they give you pills or syrups!
If you need a syringe, anyway, don't be scared, I had 3 operations and I think...yes, lots of syringes, and I'm still here! It's only a little *Pic* and it goes away!
And don't drink too many "Healthy Sport Drinks", instead, drink Orange Juice or Fruit Juices, it's healthier than every other drink!
I hope that your sickness will go away, let me know!
Bye!
