Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain in case if you are tested negative for herpes in your second test and your husband is also clear ad does not have an infection then your chances of infection seems less until you are not exposed to infection with some other infected individual or infected things like glasses towels etc..
The peeling of the lips can be due to
chapped lips or can also be due to a condition known as Exfoliative Chelitis..
I would however suggest you to
consult a Dermatologist and get evaluated and he can advise you tests like repetition of herpes virus tests like antigen antibody reaction, viral culture while testing for exfoliatve chelitis that can be due to bacterial or
fungal infection..
In case of herpes you will be advised oral as well as topical
antiviral medication like
Acyclovir, Valacyclovir etc..
In case of Exfoliative chelitis application of petroleum jelly and also Tacrolimus and Marigold ointments are found effective..
Drinking plenty of water and in case of bacterial or fungal infection treating the same can help..
Hope this information helps..
Thanks and regards.
