Brief Answer: Unlikely... Detailed Answer: Hi and thank you so much for this query. I am so sorry to hear about what your father has been experiencing. For sure I cannot tell exactly what the problem is but audible wheezing points to respiratory obstruction/congestion of which the most common cause is asthma. If he has not had this before, then cardiac causes need to be investigated. Lungs cannot be clear with audible wheezes. Stethoscopes simply amplify the sound and it would not be logical that a sound which is audible enough to the ears would be absent to be reported as clear. The difficulties to get upstairs associated with a cough could be suggestive of a failing heart. However, you would need to get hi fully evaluated and treated for what the cause is. I have not gotten any information suggesting that he has an infection that could have justified antibiotics. Please, is he able to lie down flat without need of pillows or raising the head of the bed? Do you think the cough could be worse in a flat position than an upright position? I hope you find the above helpful. I wish your dad well. He need to get well evaluated for I strongly think his problem has not been completely diagnosed and managed yet. Feel free to ask for more information if need be. Thanks. Dr. Ditah, MD.
