Hi, thank you all in advance for your help. I don't believe I have herpes, but I am still worried none the less. I have a few very very small blisters (much smaller than the point of a pen) on my lip.. they are not painful and do not appear to be crusting over. However, they are not going away. Here is my situation: I currently have strep throat and have been on penicillin for the last week and a half. I got these blisters after I gargled warm (well kinda hot) salt water.. the weird thing is they havent gone away. I'm wondering, could this be because of the strep throat, the gargling salt water, or the fact that I've also been taking a lot of airborne/emergenC? The blisters are clear and once again very small, some of them are actually so small they just look like little bumps. I've looked at all the herpes pictures and they really don't look like it, but I'm still quite worried. Any help is greatly appreciated to help ease my tension!!! Also, is it possible to have herpes on your throat and what would it look like? Thank you!!!
