Gus:
The medicine you took was probably Famvir, and I'm sure it had no long-lasting effects. It sounds like you do indeed have mild eczema-the pictures they show are always the dramatic cases. This is a skin sensitivity which often affects people in cold, dry months, but some people get it in the humid times. I wouldn't think about it too much, if I were you. Just get some simple and effective medication, like a prescription-strnght cortisone cream, and use it whenever you itch. Also, an over-the-counter itching lotion like Sarna or Pramegel or Benadryl may help you stop scratching. Otherwise, ignore it, is my advice.
Best.
