From a legal perspective, these are not damages you can recover in a malpractice case.

Then you should undoubtedly rescind the offer and live elsewhere.

You can sue them in small claims court. Take pictures of what happened so you have proof. See a doctor.

Unless the attorney lives at the courthouse there is travel and preparation involved. And they likely waited a couple of hours at the courthouse....

This is not an ethical issue. If you are still within the time constraints you can file an appeal of the decision.

This is a general Q&A forum. Don't post your or the other person's PII on here. You need to retain a local attorney to defend you.

I am not a doctor, but it is unlikely to the extreme that one bite caused such an immediate negative reaction.

I don't see how. You opted to not get insurance. That's on you.

It is quite possible. You need to make sure you have a good attorney, and your parents need to be involved.

No this is not a case. Everyone knows Walmart requires you show your receipt. That's one reason I don't shop there.
