Hi
Thanks for the query

You have provided a very detailed history which is quite helpful in identifying your problem. The chest pain especially on the left side is always taken very serious because of the heart lying in the chest cavity. The most of the chest pains are often very confusing as most conditions have similar presentation like in stomach ulcers, heart attack and plueritic chest there is left sided chest pain which radiates to back also which is where confusing for the doctor to diagnose without proper history, examination and some necessary investigations.

In your case you already had history of lungs disease plus you are also a smoker and you have an age of 37 in which there should be no heart problem ideally but you do have shortness of breath on exertion as by lifting weight like your daughter and you are also responding to aspirin.

All these features are suggestive to two things which probably could be. The first thing is your lungs as you might have relapse of disease or you might have developed plueritis but still the confirmation can be made on an X-ray chest and the second is obviously the heart which causes similar pain in ischemic conditions or pericarditis but exaggerates with exertion and often very much disturbing and causes anxiety also. So, an ECG is recommended to look for the cardiac problem. Additionally Aspirin is a life saving drug in heart pains as relieves ischemia by its anticoagulant action and also relieves pain.

If you still have some query, feel free to ask

Thanks
Regards
