Went back to get my other knuckles done and for some reason ended up with a hole on my pinkie! 
Several holes actually and it REALLY STINGS
My thumb still looks exactly the same as the last time I posted. One scab has fallen off but the rest are still there.
@Bono sorry to bother you but I am worried so was hoping you could chime in with your opinion.
It felt like I had burnt myself for a good couple of hours but the pain has subsided now.
Just worried about it scarring as time goes on.
Oh my, NEVER think that you’re “bothering me.” That’s why I’m here on Hairtell with all my other zappers. Frankly, and it may just be the excellent photo you’ve taken, the treatment looks a bit “too much.”
Like any body appendage, that is “just sticking out there” it has a somewhat limited blood supply. For that reason, for example, physicians will not inject Lidocaine with epinephrine on fingers because the “epi” constricts blood flow and can further exacerbate healing. So, they use Lidocaine (blue) straight: no “epi” and shorter anesthetic effect.
In all cases, therefore, the reaction on fingers and toes is always a bit alarming. And, the healing takes much longer than on other body parts. Overall, I still think you are going to be just fine … but there are many weeks ahead on this. (Normally people aren’t too concerned with their toes … for obvious reasons … but the finger are “right out there” and can mandate an explanation to others around you.)
I wish I could tell you that this will all go away in a week or so … but, that is not the case. Just sit tight and try not to focus on the big fat scabs that will be forthcoming!
Note to my buddies: If ONLY we still had REAL tapered needles … and used properly … this sort of after-effect would not take place. Maybe a well-placed insulated needle would be appropriate … IF WE COULD GET THOSE AS WELL! The manufacturers have let us down!
Thank you 
your comments are a little ray of sunshine in my anxiety clouded mind.
The offending ‘holes’ began to ooze but have finally scabbed over. The pain was something awful though, felt like a nasty burn. It throbbed for hours!
Luckily it only seems to have happened on only my left pinkie, all other treated knuckles are okay (albeit more sore than usual).
I spoke to the lady I see and she was concerned too so next appointment we’ll have a chat about what went wrong for this to happen.
Probably… I used numbing cream and she didn’t adjust the current to accommodate.
Keeping the area clean and using only aloe gel.
