Hello and welcome to HCM
The scabs in your nostril
are due to frequent picking of the nose. The scabs are formed due to injury
to the delicate mucosa of the nose. Due to the injury there is increased mucus discharge in order to protect the mucosa from further damage. The drying of the discharge leads to formation of scab.
Repeated picking of nose removes the scab and thus again an injury-mucus discharge-scab formation-removal of scab and so on. the vicious cycle begins.
In order to overcome this problem you will have to halt your habit of nose picking and try putting some wet gauze pieces in your nostrils for some time to keep the mucosa wet and it will aid in healing too.
The presence of yellow-green discharge point to infection with pseudomonas
. Pseudomonas is a bacteria which produces yellow-green colored discharge.
Get the culture sensitivity done and take appropriate antibiotic.
Thanks and take care
