bump on chin after treatment

I had a half hour treatment done on Monday night. Tonight I was cleaning the area with witch hazel and noticed my chin was a little sore. I have a hard lump forming on my chin on the left side, it’s sore like a pimple but feels kinda hard and is about the width of a pea. Any ideas?

I’ve been following all the after care, but I did go for a jog last night.

Oops! Once in awhile a pimple happens. Don’t mess with it, but do call your electrologist…they might say to use heat (warm washcloth), or tea tree oil, or campho-phenique, or something else…

The lump away within 2 days but didn’t form into a pimple. Starting yesterday I had a smaller lump in a different location close to the first one, same thing, feels like a pimple forming, but I find it itchy too. Both times the area is a little swollen.
Is this something I should worry about?

I also stayed red a lot longer this time it seemed to linger on the chin area - this area has been treated the most, could I be having a little bit of over treatment?

I also noticed a couple pinpoint red marks in a couple of the areas treated. The don’t look like scabs, just little marks. Anyone know what these are?

I have a treatment tonight and will ask her about this. Just wanted to check here first.
