I second MRSA (not a virus but an antibiotic resistent bacterial infection) or some sort of staph infection. What about chicken pox? Ever had it as a kid?
And, I do have a friend who can not use Clinique anything. She gets terrible rashes and sores from their products. Interestingly, she also got a weird skin infection on her face two years ago. She doesn't know how. It was some rare antibiotic resistent skin infection, but not MRSA. It took a long time to heal, but she was told it will always remain dormant in her system. EEK.
Whatever it is, I'd get it checked right away. You wouldn't want to be sporting something communicable or something that requires extreme hygiene on your part so others won't be at risk. There is also the possibility you need antibiotics...the sooner you get em the better.
