Hi, am just getting over a pretty bad cold I have had for the past week. My lips have been very dry and today I started having discomfort on the Left side of my bottom lip. I now noticed that I have little white bumps, almost like pimples, on the outside AND inside of my bottom lip, both on the left side. I do not know if this is just a symptom of my very dry lips from being sick or if it is something of more concern, like an STD.
