What causes a blister on the neck in a child?
Patient: Hi, I have genital herpes that was diagnosed 18yrs ago. i have a genital outbreak about once every 18mos or so and last week I had a lesion on the back of my leg for the 1st time ever. I am concerned about my 9mo old daughter....she had a single blister on her neck/under her jaw that never spread, but is still present, yet smaller now, after 5 days. On day 3 of me watching that one closely another one popped up on her leg, just above her ankle. I am terrified, (and maybe a little paranoid), that this is herpes. I covered the one on her leg with a waterproof bandaid to prevent spread of any juice if it pops. It, like the one on her neck, hasn t spread but has a reddened periphery and is definitely a little blister. Because of the new location of MY leg lesion, I didn t notice it as early as I do my genital outbreaks and am afraid I spread it to her somehow. BTW, I had a normal vaginal delivery 9 1/2 months ago, no outbreak at that time, and was taking a prophylactic dose of valtrex daily for a week prior. Doctor: Hello,  Skin conditions are best diagnosed and treated after seeing them directly. May I suggest you upload some images of what your your telling so that we can guide you better.
