My 10 mon old allergic to Amoxicillian, How bad does the rash get? Do you know where I can find photos?

I was allergic to it too when I was little and all that happend to me was I got a rash all over my body but it wasn't like drastically red or even swollen. I never got sick or had an upset stomach but my mom also called the doctor as soon as she saw it so we may have just caught it in time.
