Thanks for allowing me to work with you on your health question. I will do my best to answer all parts of it.
Let's start with what happened: Your doctor is right, you suffered from anaphylaxis shock, which is a whole body reaction (allergic) to a substance.
With a jalapeno pepper what most people don't think about is it is not the pepper itself that is the culperate, but the OIL.
If you have ever tried to get rid of the hot of the pepper, you will notice that not even water puts it out as well as one might think and that is because water and oil do not mix. Usually folks will tell you that it takes bread (solid, flour) to get rid of the oil in the pepper to get rid of the "hot"...and that is why. It is coating.
That is why the reaction you are having is taking a while to "reverse" and responde to the medications. It is the oil. Your teeth hurt and feel broken out because of the oil coating them and if the gums around the teeth have any openings or sores, the oil has gotten in. Since you are highly allergic to it, it will really work on you hard.
I am unsure as to why the Valtrex was given? He would know. The other medications I can see with the reactions.
Since you have such a high reaction to jalapenos I would ask the doctor for a EPI-pen prescription. This is a pen that is actually a shot. Incase you are ever accidently exposed to this again, you can be given the shot immediately and reaction is stopped fast.
I would also now let this be a part of all your permanent records. It could be life ending for you since it affects your breathing.
