Just as the coughing can be caused by swelling and restriction around the vocal cords and airways, so too can this cause a wheezing sound when breathing and even a change in voice. This is of course because the air is escaping through a narrower passageway. If you try blowing air through pursed lips, you’ll notice this results in a similar squeaking sound.
This can sometimes make it somewhat difficult to breathe, though this shouldn’t be the case. If you notice that you or your young child find it difficult to breathe, then you should seek medical attention as soon as possible.
Likewise, it is important that the wheezing sound is being made during the inward breath. If the high pitched sound is also heard when exhaling, then this is a sign that the issue may become dangerous and you should see a doctor right away.
It’s also very important to look for signs of bluing skin around the nose, mouth, or fingernails. This suggests that the patient is not getting enough oxygen, and again it requires immediate consultation with a doctor.
