Thank you for your question.
I am Dr Saha, I shall try my best to help you.
Besides Herpes there can be a few other possibilities.
This can occur with dermatitis.
Contact dermatitis with an irritant or allergen can cause it.
Bites as from bed bugs, scabies can also cause it.
Bacterial infection usually causes pus filled ones which seems unlikely if the fluid is clear.
Antihistamine creams like benadryl can help if it is due to an allergy.
Zyrtec tablet can help as well.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
