If your doctor swabbed the lumps, they probably checked for herpes. You can call and ask to see if they did run a herpes test.
It can be an abscess, its hard to say for sure what it is. As I have not seen the said lump. Get a second opinion just in case, and call the doctor's office to see if they did run the herpes test. If you're still paranoid, it may be herpes ask for the blood test. There are 2 kinds of herpes. Herpes type 1 are cold sores, that you usually get around your mouth. Herpes type 2, is the one you're worried about. The blood test will tell you which one it is if you do have it.
