Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain and presentation of symptoms it seems that you are suffering from a
HERPES VIRUS 1 infection causing
cold sores and the symptoms of
fluid filled blisters appearing is clusters is a hallmark sign of herpes infection.
Although it is a self limiting infection and the blisters resolve in a period of approximately 2 weeks time..
But there can be repeated recurrences..
You should consult an Infectious Medicine Specialist and he can do a clinical examination and necessary laboratory investigation like Viral culture, antigen-antibody reaction, polymerase chain reaction etc for confirmation..
If Herpes is confirmed you will be advised oral and topical anti-viral medications like
Acyclovir , Valacyclovir etc to prevent recurrent infection..
Hope this information helps..
Thanks and regards..
