[|Human|] I have been experiencing episodes of shortness of breath, tight chest and the odd pain in the ribs when breathing. A recent blood test and X-ray were clear. A pulmonary function test has been ordered. the symptoms occur mostly at night. could this be an allergy?
[|AI|]  Although you have not mentioned the frequency and duration of symptoms, it appears that there is a possibility of asthma-especially as you are getting symptoms on lying down at night. Your Physician will evaluate your pulmonary function tests to confirm the diagnosis. And among the most common cause of Asthma is indeed Allergy. It would be good to avoid dust, smoky surroundings, overcrowded places, and keep the bed linen etc. free of bugs, cockroaches as animal dander is well known to precipitate symptoms. While you wait for pulmonary test results, you can safely take antihistamines Chat Doctor.
