There is a form of herpes, Herpes Simplex 1, that only occurs around the mouth -- and sometimes up into the nose. (Herpes may also occur in the eyes, I believe that is the same strain.) Herpes Simplex 1 is most often referred to as "fever blisters". It usually, but not always, occurs as a cluster of small blisters.
I've had it all my life -- I've read where it is hereditary rather than something you catch. It is not a STD, although if you have blisters or the pre-blister itching it can be transmitted to the genitals thru oral-genital contact.
It usually does not flare unless a person is running a fever or is under stress, and does look significantly different than a cancer sore, and has a very distinct itchy/tingly/burning sensation at first. My flares increased significantly once I developed Lupus -- I now take a daily medication, Valtrex, to avoid flares of fever blisters.
If you do not see your doctor soon, try and take a picture (as close up as you can get) to take to "show and tell" later. It is not something to worry about
-- and can be controlled if you start getting them too often.
I suspect it is a reaction your body is having while it gets used to your new medication, and that you may never have another occurrence after your body gets used to the med.
PS. I've also had cankor sores, and they do not have the burning/tingly sensation that fever blisters do.
