Just started week 8, averaging 15 hours per day so far and using a far bit of manual suction (just less than what leaves a hickey!) - ramping up slowly over the session. I think I'm getting a puffy sternum, not painful to the touch or on deep breathing / excercise. Wasn't sure it wasn't my imagination but put on a fairly tight bra this evening and it went in underneath the ?raised area leaving about 0.5cm puffing out. Have googled costochondritis and don't have the pain but it is a swelling in that area. It seems to be where the domes meet in the middle and I have overlapped them quite often as I have a small frame.

Has anyone else had similar? Did it go away? If it's not painful does it matter?

yup, i have. twice. but it was gone quickly. first time i put the domes back on after 6 hours and tryed to make sure that area isn't pressed on but it was still swollen and poping from under the silicone. it was gone by the time i took them off. second time 2 days ago but i took a 14 hour break and it calmed down. i have no ideea what it is. may be the tissue covering the bone and the pressure was somehow too high on the area. i was swollen right between the boobss, starting from the middle to the lower end of the sternum.

anyway i don't think it's anything to worry about.

Thanks, for some reason it's more obvious at the end of the day than when I take the domes off - maybe because it's more obvious between empty boobs than swollen ones! At least something's happening!

right after u take them off the domes were pressing on the area and there was no room for swelling so that's normal. a couple hours after it's at it's peak in my case but like i said it goes away in a day or so.

Lay off the extra suction for a couple days just let the smart/sportbox do the suction. give your skin a chance to rest a bit without wasting weeks by loosing 2 days or more without wearing the system.

I have not had it happen to me yet but i am fairly broad across the chest :( just wish i had projection to go with it. :P.

I hit 3788 total hours today 248 days into it 15.27 hours per day average 1687 hours to go for goal. then i give it a rest.

Cheers to growing ladies. good luck stick with it.
