enigma:
i would suggest putting your old jewelry back in immediately, and probably give your ears about 6 months before trying to stretch back up to 12g.
oh, i was wondering, did you use any lube while stretching? i found that using a little bit of antibacterial soap and water on a taper made stretching very quick and painless without any irritation. just be sure to rinse it out really well afterward.
Per your advice, I've put some 14g SS claws back in. They're not as dainty as my spirals so my lobes can breath a little. 
No lube. Wow... I was really bad when I did the stretch thinking that it would not be any problem. I just jabbed the claw in like a regular pair of earrings. I felt a little throbbing, but didn't really think much of it since I've felt that same pain going from 18g to 16g before. I didn't know it was going to be like this. I think I have a bad ear... my right ear seems to be a little more finicky than my left ear. I'll keep the soap and water trick for next time. I might even just use jojoba oil for my bad ear.
Music.and.holes:How long have you had your ears
pierced for? Stop the Neosporin! Even though it is for healing, it
says not for punctured wounds, this includes piercings. I'd put in your
14 gauge spirals in if you have nothing smaller than that. Do SSS(sea
salt soaks) about twice a day. Its about 1/4th teaspoon to a cup of
warm water (the ratio changes, but thats what I use). Try to wait a
minimum of a few months before stretching up. You do not need to use a
taper, especially at such a small size, although this is up to you. Its
best to stretch right after you come out of the shower so your lobes
are nice and warm and have good circulation, then lube up the spiral
you have or any other jewelery you want in, and slip them in, the
slight pressure/ burning is pretty normal, although there should not be
any real pain, blood or require you to push the plug in with force.
Good luck! =)
I've had my ears pierced for almost 20 years. I started with the gun (they were 20g or 18g... it was the 80s). What was weird is that I went from 20g to 18g with no problems, 18g to 16g was a little painful but I got over it within a day, 16g to 14g with no problems (bought the 14g spirals at the mall and stuck them right in). When I put in the 12g this time, the feeling felt like when I went from 18g to 16g with some throbbing. I didn't think much of it until the right lobe swelled up a week later. Not sure why the 14g to 12g was so wonky. I'll do SSS 2x a day and move along with the 12g in a few months.
I'm so bummed it didn't work out because I have some Little 7 Preistess coming on the 6th
. I guess good things come to those that wait.
Thanks enigma and music.and.holes! I really appreciate your help!
