Could the Alloderm have been sewn too tightly? Is their a way to fix this problem with a revision surgery? (photos)

These symptoms should decrease as time passes.  The tissues relax.  Using a relaxant can help during this time.

This tightness feeling can happen, and does fairly often.  Good news is, it will go away, and your tissues, including the Alloderm, will relax fairly soon.  In the meantime, you can take some muscle relaxants if you're having muscle spasms to see if that helps.

While Alloderm does tend to stretch over time, it is not likely the Alloderm specifically that is causing this feeling of tightness. Most likely this feeling comes from a combination of the implant or expander under your muscle and the size or fill of the expander or implant that is there. Oral muscle relaxants such as vistaril or cyclobenzaprine can help in the acute period of time when you have these feelings of tightness, and this almost always gets better in the first 4 weeks after surgery.
