Allergy identified and dealt with

So, the allergic reaction caused a skin rash that no-one at the hospital noticed, and the skin rash escalated into something more severe. By afternoon, the rash had turned to pustules and they had begun to pop. Thankfully, my sister spent most of the day sorting things out, and after a trip to hospital emergency, he's now been hooked up with Benadryl and a different antibiotic. Things should start to improve from here.
