I did that too about the sound when I had pneumonia; it sounded unworldly as if coming from somewhere else and couldn't believe it was me. I can relate to that. It took some time to heal but hope you are on the mend soon. Fluids and rest helped a lot. Please take good care.
Also, ask the doc if a humidifier might help. It and warm/hot showers seemed to help ease things. Warm, moist towels on my chest OR a heating pad on low to the chest and back helped ease these muscles too from the coughing. Hang in there! Sending wishes for speedy recovery.
