Haha, thanks for remembering me, scruffy!
My microdermal (i only have one) is placed so when I'm wearing a plunge bra (like this: http://www.lanebryant.com/product/Cacique/Bras/plunge/Smooth-plunge-bra/36854/pc/4043/pslot/3/sc/110/c/4044.uts) it's about 4 inches above the middle part. So it's pretty well settled in my cleavage. I'm a 44D btw.
Like others have said mine healed up super fast. The first couple days I was wary of sleeping on my side, so I tried to sleep on my back. I'd usually wake up on my side and it would be a little sore, but the soreness went away after a short SSS. After about a month I was able to sleep on my side with no trouble.
I've had it for almost a year and a half, and overall it's settled pretty well. When i stand up straight or if i'm not wearing a bra, it sits about a millimeter off my skin. Pretty sure it's cause for me my sternum is kind of a fatty area and therefore increases and decreases in thickness depending on how i'm standing.
Mine also acts up along with my cycle. Pretty much every 28 days it will get crusty and i'll kind of have to gently push on the skin around it to get the lymph out. Other than that the only time it gets sore is when i'm reaching across my body with one arm for a long period of time. It just starts to feel uncomfortable.
Alright I've talked enough. Lemme know if you have any other questions, k?
