Im 71, havent smoked in over 35 years.  It seems like when I go outside for a few minutes I get pain in my upper chest.  The outside temp is rather cold, maybe 35 or so.  When I come in and sit down the pain lets up in a few minutes.  It seems like it breathing in the cold air.  It doesnt feel like it is my heart.  This is something new for me.
Hi thanks for asking question in Chat Doctor. Here you have dyspnea in cold air... Do you have asthma in the past.??? Do you have smoking for how many years?? Here first as sensitivity to cold you could have allergic condition that might be undiagnosed like asthma. . Here also chance of bronchitis like resp condition can lead such presentation... So for these resp causes chest x-ray and spirometry useful.... Your resp examination by auscultation also has to be done.... As your dyspnea is on walking early stage heart failure causes has to be ruled out...ECG or echo will be useful .... According to cause treatment given with steroid or bronchodilators... Hope your concern solved.... Take care.... Chat Doctor.
