How to Fix Pain from Scar Tissue After Breast Reconstruction?

There are many potential causes for the pain. It could be capsular contracture, fibrosis, bony discomfort, axillary scarring, intercostial brachial cutaneous neuropathy, radiation changes, neuromas, etc.
In my experience, the most common cause is a taut axillary scar that often is involved with a caspular contracture.
Conversion of an implant to autologous tissue recosntruction may provide vascularized tissue that prevents recurrent capsular contracture but therre are many other alternatives which are less invasive albeit not as succesful.
Occasionally, I have found that performing a z-plasty on the axillary scar can provide relief of discomfort caused by a tethered scar.

As mentioned by other physicians on here, the cause of pain is extremely variable. The different causes of pain present differently. If it is true scar tissue usually time will help as well as some deep tissue massaging to break up the scar tissue. Best thing wound be to get examined by your physician and make the determination of what is causing the pain.

Pain that occurs in reconstructed breasts can occur for several reasons. Most commonly, pain can occur in a reconstructed breast that develops capsular contracture. Pain can also occur secondary to scar contracture, especially when there is a small amount of residual breast tissue left in place.Occasionally, the process of tissue expansion can put pressure on the chest wall and cause pain in this manner.

Although operating for breast pain does not always relieve the pain, there are some things that can be done for each of these conditions.  Replacing a tissue expander with a softer silicone implant can relieve some pain complaints. Some patients will benefit from placement of Alloderm inbetween the implant and the skin, which serves to make the skin less sensitive in some. However, some reconstructed breast pain and scarring is really bad, and can only be relieved by "bringing in new tissue," such as with a Latissimus dorsi flap.
