I had an augmentation with alloderm sling and implant. I am still uncomfortable . How long before that stops?

Most of the pain should resolve within 3-4 months, but it can take up to a year for the pain to subside completely.  Alloderm should be fully incorporated into your tissue within a year. Ask your doctor if he feels breast massage may help loosen up your scar tissue. 

Sometimes it may take as long as a year for all the scar tissue from surgery to soften completely, and for the pain to resolve. Another possibility is nerve sensitivity which can also take 6 to 12 months to resolve.

Usually it is not the Alloderm but the sutures that are placed to hold it until it incorporates. These are usually slowly dissolving over several weeks or longer so that the fixation doesn't come loose too early. A lot depends on what else was done - size and type of implants, previous surgery, etc.

You are probably sore from the sutures that were placed into the lining on top of your ribs and that is unfortunately really painful. There is just no other tissue that is as strong to hold the alloderm but it has been my experience that the pain should resolve in under 3 months.

Conceptually, the alloderm can function as an "internal bra" which supports both the lower and lateral extent of the implant, giving a fuller shape to the breast and enhancing the appearance of the cleavage area.  The material itself is very soft and is designed to be a scaffold along which your body can plant its own sells that will ultimately essentially replace the alloderm.  This process begins after the first week or so when your own blood supply grows in, and can take up to a year.  How uncomfortable this feels and how long it takes to go away varies by the individual but it's very unusual for the alloderm be felt after six months.
