usually you have to ask for the aids test. one thing that really made my frind break out with cold sores was getting a sunburn, and smoking.
keep a journal of what you do. you will find your personal triggers. until then there are many ways to combat this over the counter with stuff. in the meantime get an aids test. every time i have gotton one they sit you down in a separate room alone and have to tell you if you are clear or not and match a number to a sheet you have. its confidential. they dont put your name on the paperwork. its free. contact your local health department. its in the blue pages of the phone book.
