That seems really high for your pouch. How far out are you from your WLS?
I had a sharp poking/rubbing pain in my chest after I'd lost an amount of weight and it turned out to be a bone and the way my bra wa****ting it. My doctor sent me off for a bra fitting and the purchase of a good bra, and problem was solved
It may be your bra that is causing the pain. Have you been fitted for a bra, or are you just buying off the rack picking the size you think you wear? Going on the assumption that it is the bra that is causing the problem you should go to Macy's, Nordstrom, or Victoria's Secret and get properly fitted into the correct bra size (it really is a science to properly fit a bra.) Then stay at Macy's or Nordstrom and purchase a Wacoal bra. Hopefully that will help.
If it's not the bra, I have no idea what to tell you.
I am sure some on here has much better advice for you.
