Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain blisters inside the nose can be most probably be due to infection inside the nose and can be caused due to bacterial or viral infection..
As you also have stuffy nose it can be most probably due to viral infection causing cold sores and is caused by
Herpes Simplex Virus 1..
Other common cause for occurrence of blisters inside the nostrils seems to be due to bacterial infection caused by
Staphylococcus bacteria causing Impetigo..
I would therefore suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like nasal swab culture, nasal
endoscopy and
blood test can help in diagnosis and treatment can be planned accordingly..
For viral infection you can be advised anti viral medication like
Acyclovir..
You can also be given saline nasal sprays and decongestants to relieve stuffiness and congestion..
In case of bacterial infection antibiotics can be advised..
Hope this information helps..
Thanks and regards.
