I thought I'd start this discussion in the "adult" group cuz well..teens aren't really old enough to be getting most things done!
I remember my mom always trying to keep me from piercings/tattoos(and still does) by telling me that my healing time was going to be too long and it would effect my diabetes. I have yet to have any problems with my diabetes/blood sugars while healing..and rarely have they taken longer than the usual amount of time. I'm always really on top of things and at the first sign of infection, I go to the doctor, so I think that's why and as long as I keep doing that, I should be fine.
I have three tattoos and ten piercings. I have a bat on my lower back that's about the size of a football, "mom" with her fav flower and colour on my right ankle, and a small bat the top of my right foot. I have a double eyebrow(pierced through scar tissue from my horizontal eyebrow which rejected 5 times and re-pierced 4 times, then the anchor rejected when we tried that), two cartilage on my left ear, a conch piercing on my left ear, one cartilage on my right ear, both my lobes done once, my naval done, and as of 12:15pm today..both my "girls" are done. I have all surgical steel barbells, as I love the look of steel and it looks a lot better than having a zillion different coloured beads in my ears, etc.
I didn't have any trouble with any of them healing, except my first tattoo(the bat on my back) made me break out into a skin infection after a few days but was fine once i took anti-biotics, and my eyebrow has taken a lot of abuse when i've been drinking so it's healed but still likes to spaz at times.
what does everyone else have, if anything? your experiences?
