The swelling causes the characteristic low-pitched cough, resembling the bark of a seal. The cough is often worse at night and gets aggravated by crying as well as anxiety and agitation. The swelling also causes breathing difficulty that may produce a high-pitched whistling sound.
Apart from coughing and labored breathing, it is common to have a fever and a hoarse voice. Symptoms usually last for three to five days. However, proper healing may take more time.
During this time, some simple home remedies can keep your child feeling more comfortable and help prevent croup from returning.
Note: If your child’s symptoms persist beyond three to five days or worsen, see a doctor immediately. Also, seek immediate medical attention if your child develops symptoms like severe breathing difficult, difficulty swallowing, rapid breathing, rasping sound when inhaling or exhaling (stridor), or dark, blue-tinged skin near the nose, mouth or fingernails.
