Hi, thanks for using healthcare magic

Based on your response, if you have not been exposed to amoxicillin, you have another allergy.
It may be one of the medications given or food consumed.

The use of the benedryl and calamine is appropriate but if the allergy is not responding to this then you may need to use steroids.
Though topical steroids would help to reduce the inflammation, based on the severity, you may need oral as well.

It would be best to visit your doctor

I hope this helps
