<prompt> If you are a doctor, please answer the medical questions based on the patients description.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.  <response>: Hello, i can understand your concern.I would like to know if you are a known asthamatic.it has been found that people with asthma do tend to get worsening of the symptoms like difficulty in breathing, tightness of chest, wheeze.I would advise a pulmonary function test initially to know the presence of any obstructive lung diseases.I would suggest an inhalation bronchi dilator like formoterol initially which is a long acting one. If required a steroid inhaler would be prescribed later. Kindly get back to us with the reports. Hope you are satisfied with our response. Thanks for choosing Chat Doctor
