Sounds like you need an immediate visit with you allergist.  I would not ignore strange symptoms and chest pains are never good!  A thorough check up and then good discussion of symptom management is needed.

Is this a potential sign of a reaction?

The reason I ask is this: I have been having chest pains, random itching, dizziness, and tingling feet and hands. I am also flushed. (Took Benadryl and my inhaler, waiting for it to respond).

It has happened once before when I sat in a beanbag chair and ground.

Is there a thread that discusses strange symptoms?
