continued swelling 24 hrs after nape treatment

I had a short treatment to start tidying the nape of my neck and the slight swelling remains almost 24 hrs later.

Its not terribly visible but should I be concerned? I haven’t had this strong a reaction anywhere else.

I want to continue treatments there but I wonder if this means something.

thanks!

I have been getting that treated as well…for some reason, it is a bit more sensitive than other parts…when it bothers me, I put a little ice on it, but it should start going back to normal in the next day or so.
