Hi! I am 43 years old, 125 lbs and in good health. I have some food allergies, and a mold allergy. It has been very hot and humid out on and off all summer. Each time the temp and humidity rise, I have a really hard time breathing. Feels like someone is sitting on my chest, and it is extremely painful to take a breath. It goes away slowly when I get into an air conditioned area with lower humidity / lower temp.
