Thanks for writing to us about illness of your boy friend.
I have gone through your query regarding nasal obstruction
, nasal discharge and bleeding from nose after exposure to irritant component of paint.
I would like to tell you that there are irritant components in paints specially is spray painting which are responsible for inflammation of nasal mucosa, thus mucous membrain gets swollen, congested and having tendency to bleed. The infected discharge forms scab or crest at the nostril
which on removing may bleed.
This is usually a self limiting condition and your friend is now advice to take- Antibiotic, anti inflammatory, decongestant and steam inhalation.
I hope your friend will be benifitted by above treatment .
