Sorry to hear about your ongoing pain.I had a mastectomy in 2010(previous lumpectomy,full node clearance and radiation in 2003).I get a lot of discomfort- like I have a rolled up newspaper under my arm and duck tape across my chest.My surgeon says I have adhesions and lymphoedema in my armpit.She said that a Diep recon might actually help the chest discomfort.I have a friend who gets dreadful nerve pain under her arm and she says the drug, Lyrica has helped.So I'm not sure exactly where your pain is or what recon type you want?It's good you've had some improvement with the pain.Let us know abit more detail and perhaps some other ladies here can also help you.
