What Causes Burning Sensation In Chest And Breathing Difficulty?

I am a hypertensive person on lysinopryl/HCTZ with a severe latex allergy. I recently had an allergic reaction to latex paint in my school building. The school was being painted on the inside while the kids and teachers were in the building. I was O.K. most of the day until the concentration of paint increased. (2-doors down from me) I started having burning in my chest then pain in my back, followed by a scratchy throat. I left to see a doctor. By the time I made it to the doctor, my throat started closing. I was given a breathing treatment and 2 steroid shots. The next day, I woke up with swollen legs and arms, along with heart palpitations. I was sent to the ER where I received more steroids and oxygen, along with an x-ray. The next day, I had a panic attack and nearly lost consciousness and received another breathing treatment and an inhaler. Later the same day, I found out that the x-ray showed that my heart is enlarged. Yet, I had an x-ray and MRI only 3 months ago and no such thing existed. **Could the paint fumes have caused me to have all of these weird things happen all of a sudden?
