HI DOCTORS, I AM 34, HAVE BEEN SMOKING FOR 13 YEARS, VERY SLIGHTLY OVERWEIGHT BUT GENERALLY HEALTHY. I HAVE HAD THE FLU RECENTLY, NOW I HAVE EXTREME TIGHTNESS OF MY CHEST AND WHEN I SIT UP I AM FINE, BUT WHEN I RECLINE EVEN SLIGHTLY OR LIE DOWN, I CANNOT BREATHE, I COUGH AND HEAR CRACKLING SOUNDS FOR A FEW SECONDS AFTER I EXHALE, EVEN IF THERE IS NO BREATH ANYMORE. MY UPPER BODY MUSCLES ARE SORE FROM ALL THE COUGHING, AND WHEN I SIT IN FRONT OF MY TUMBLE DRYER THE STEAM COMING OUT MAKES ME FEEL BETTER. I AM OKAY BUT I CANNOT LIE DOWN TO SLEEP SO I AM GETTING SOOO TIRED. CAN I USE AN ASTHMA INHALER OR WHAT? THANK YOU FOR ANSWERING....

### output:

Thanks for your query. Your symptoms are suggestive of probable asthma. If I were the treating physician I would first confirm the diagnosis by objective test(spirometry). Then I would advise as follows:>Avoid triggers (e.g.smoking, cold , dust etc.)>Bronchodilator (e.g. Salbutamol) inhaler as required to relieve chest Highness.>Steroid inhaler to control attack. So my opinion is :please meet your local doctor/respiratory medicine specialist to confirm the diagnosis and get treatment henceforth. Hope this helps you. If you have additional questions, please do not hesitate in writing us. Wish you good health.
