My Husband keeps getting these blister like outbreaks on his nose. Normally caused by weather change. Sometimes it is months between outbreaks , this month alone its happened twice. It starts with a small water like blister, breaking , then turning into a scab. What could this possibly be? He is currently 30 years old. This has been happening for about 5 years.
I can understand your concern and for these blister like sores on the nose, cold sores caused by HSV 1 should be ruled out.
The herpes simplex virus (HSV) can cause blisters and sores almost anywhere on the skin and HSV1 causes them on the face and mouth. What your husband may be having is recurrent infection which can occur after exposure to the primary exposure.
To confirm the diagnosis, swab from the infected skin (culture) may be taken and sent to the laboratory for analysis. Oral anti-viral medications such as acyclovir, famciclovir, or valacyclovir have been developed to effectively treat herpes infections. If HSV 1 infection is confirmed then these drugs can be taken.
Hope that this information helps and hope that you will get better soon.
