Pain and numbness after breast surgery…
If this is the case, it is possible that removal of the nerve, may alleviate the painful sensation. If you have numbness present, sensation may or may not return over the course of months/years.
Otherwise, numbness/pain may be related to pressure from a breast implant on the overlying tissue; this may be seen with breast implant displacement or malposition. Again, hard to say whether this is relevant in your case or not.
Your plastic surgeon will be your best resource; with careful physical examination he/she should be able to provide you with more precise information.
