Brief Answer: Avoid using decongestants. Detailed Answer: Hello, Thanks for trusting us with your health concern. You have a dry nose which is causing the repeated built up of thick scabs in the nose creating breathing issues. Extremely hot or dry climates (as well as air conditioning) can result in your nose losing moisture and drying out. Dry nose is also a common side effect of certain medications, such as some antihistamines and decongestants. Nasal sprays that are used to relieve a nasal congestion can cause a dried out nose or rebound effect when they are overused. Upper respiratory infection (i.e., rhinitis) and hormonal changes also cause a drying out of mucous membranes in the nasal tissues. You need to turn down heat in your home and use a humidifier. Saline nose sprays can be found over the counter and can be used to keep the nasal membranes moistened. Petroleum jelly is very viscous and can easily be applied to the inside of your nose to help keep your nose dry. Avoid using the decongestants. Please feel free to discuss further.
