Reasons behind Nose Blisters
Most often, nose blisters are actually fever blisters, triggered by a virus called herpes simplex virus. The condition is also know as cold sores and usually appears on the mouth area, even though it can be found in the nose, where the virus finds an ideal environment for flourishing. So, due to the delicate nature of the inside of your nose, the pain these blisters deliver is more severe than the pain of cold sores located in other areas.
Fever blisters do not heal fast, especially when they are found in the nose. Once the virus responsible for this condition enters the body of the victim, it remains idle in nerve tissues. Then, when the conditions are adequate, the virus reactivates and starts affecting the person again.
As far as bacterial infections are concerned, the one affecting the nose is called impetigo, triggered by Staphylococcus bacteria multiplying in the hair follicles located on the inside of the nose. When this happens, nasal follicles become red and filled with pus, evolving into blisters. When the blisters burst, the area gets dry and a crust forms. Usually, the bacteria reach the nose due to nose picking and contaminated fingertips.
Finally, blisters inside the nasal cavity may form in allergic individuals due to inhalation of the specific allergen.
Treatment for Blisters in the Nose
The treatment depends on the underlying cause behind the infection. For example, if the infection leading to blisters in the nose is bacterial, antibiotic ointments are used for treatment, along with oral antibiotics in some cases. However, antibiotics are useless against viral infections. Rather, these are taken care of by anti-viral medications such as acyclovir, famciclovir and Valacyclovir.
Alternatively, ice application is known to reduce pain and quicken the recovery. Additionally, taking vitamin C and zinc supplements can also be a helpful step to take.
Finally, keep in mind that Staph bacteria as well as Herpes simplex virus can be spread to other people. So, keep the area clean and disinfected and if you touch blisters with hands, wash these immediately.
