It's interesting how pain and tissue expansion are related. Sometimes it is painful for a few days and sometimes not. Be sure and discuss this with your surgeon. Maybe you need more time between expansions or a smaller volume expansion. If you are developing capsular contracture that is resisting the expansion, you may need a surgical procedure before further expansion. Pain control otherwise can be obtained from various type of pain pills and sometimes cold packs will be of help. Doctors are interested in keeping their patients as comfortable as possible so please speak with your surgeon first. Too much pain may be a sign that too much pressure is being exerted against the ribs and that can actually deform the ribs, negating some of the benefits of the expansion.
