Hi @lsittll
I am very sorry to hear that and can imagine how anxious this leaves you, something that can even trigger seizures.
As you know, I am not in the US. But in case this happens to me here in Brazil, I would first get in contact with Abbott, explain them my situation and ask for some help. I would also talk to my doctor asking him for his support. In case this would not bring good results, I would make a public complaint. Here in Brazil we have a site where consumers can post complaints about products, services and companies. Usually, it works pretty well, getting replies from the companies. When this does not work, I go consumer protection agency from the government. I am sure you also have those means in your country.
I hope this helps you a bit in this situation.
My best wishes!
